This applies only for osu!-Standard! I don't have much experience with the other modes, so I can't tell!

I recognized that many mapsets still have problems with difficulty spreads, although they are following the current rule:

Ranking Criteria wrote:

The difficulties in the mapset must be in a consecutive order. The order can be seen in the chart below. If your mapset has two difficulties, one of them cannot be an Insane or Expert. The lowest difficulty must be below 2.0 stars. The difficulty level of Taiko-specific and osu!mania-specific difficulties must also follow a well-designed spread and might contain an Hard/Insane only, if there are standard difficulties present. In CtB, the spread evaluation is upon the BATs discretion. The difficulty spread is determined by the map's star rating. A map falls under a certain difficulty when having a specific star rating:
  1. Below 1.5: Easy
  2. Below 2.25: Normal
  3. Below 3.75: Hard
  4. Below 5.25: Insane
  5. Above 5.25: Expert
The main problems I can see are:
  1. The easiest difficulty is still too difficult. This applies often when players choose not to have an Easy and just rely on a Normal | Hard | Insane-spread. For example, they use too high slider velocities, too complex rhythms or very cluttered placement, which makes the easiest difficulty of their mapset not understandable for most of the newer players.
  2. Often, players are too lazy / just don't want to have an Easy difficulty in their mapset, but they have a very difficult Insane, usually around 4.75 to 5.25 stars. Since the Normal has to be under 2 stars, they have to create a Hard difficulty around 3.25-3.75 stars for an appropriate spread. The problem with that is, that the gaps between the difficulties usually are very big then, which is also considered as a bad difficulty spread. For example, the Insane uses very much of 1/4, while the Hard doesn't use any 1/4 - It is bad, because Hard players can't prepare for the Insane difficulty then, but they can't make the Hard more difficult by adding 1/4 because in this casethe gap to Normal would be too big.
Both points are often connected to each other.

My suggestion, to prevent both issues, is a guideline (because it doesn't have to apply for all mapsets):
The diff spread should be reasonable. If your Insane difficulty's star rating is over 4.5, it is recommended to include an Easy difficulty in your mapset, so that the gaps between the difficulties won't be too big. This way, you will make your mapset accessible for every player.

I hope you understood and respect my opinion. Please, tell me what is your opinion!

The discussion in the thread went far from what I wrote here and I also don't even agree with it anymore, so it's pointless to read the above wording.

Nobody cares about diff spread x)
But yeah it will be fine if there is an easy diff to balance a set, and which allows the mapper to be "more free" with Normal and Hard diff concerning diff spread. (he could make a harder normal/hard than a traditional one, as i always do)

I agree with this. Almost, if not just all songs can have an Easy mapped on it. Might as well enforce Easy diffs to be made too, but that's another story. For this, I can see nothing I should oppose (this can really help in making better spreads for maps!), and thus I'll give this a full support. Trying to make a Normal below 2 stars usually might end up making it a little too easy anyway, and it can limit what can you usually use in a >2 star (usual) Normal diff.

I'd say it should be re-worded to somewhat like this:

The diff spread should be reasonable. Which means, that you should make your mapset playable for a wide range of players: from beginners to highly-skilled top players.

As I've heard several beginners complained about being unable to actually play some recently ranked/mapped Normal diffs with <2,00 star rating due to high slider velocity/complicated rhythm.

Hmm, about your rewording. I really want to include that with the over 4.5 stars, because it applies to the mapsets we are talking about in 99% of the cases.
But I'll take something from it and change my wording, thank you <3

I actually kind of agree. Spreads tend to have giant gaps when it's a NHI set. Enforcing an Easy on sets with harder Insanes almost automatically balances the set.

Yeah, NHI sets are kinda unbalanced :S. I also think that the Normals in these sets are far too hard for some new players, even if they are under 2.0 star rating.

Can we just enforce the fact that the easiest diff of a spread should not contain some elements like:

-Stacks
-Short spinners
-Post spinner notes
-Anti-jumps
-1/4
-Repeat sliders with over 1 repeat

And such? These things are often used in normals, but when they're used on the easiest diff it's like throwing a brick at the new players.

I don't really agree with this one, because repeat sliders with over 1 repeat could be used to avoid polarity issues.
I think you mean 1/2 reversed sliders ?

this is fine if used properly, I think.

Krisom's words can be added as explanation to the guideline. This might help people to improve their E/N diffs a lot.

I have to agree there are problems which Desperate mentioned on current maps.

[Insane]s are becoming harder and harder, consisting 1/4 slider jumps for example. To fill the gap, [Hard] has also became intensed by adding jumps or small 1/4 notes. Then mappers strike a problem: the gap between [Normal] and [Hard]. Mappers would increase spacing or sv of [Normal] to make more harder, while keeping the 2.00 star diff, and not map an additional [Easy]. I guess this made you think there should be a guideline to enforce mappers make an [Easy], right?

But the [Normal]s which are made that way can have chances to function nicely as the easiest difficulty.
Whether or not the lowest difficulty of the map is easy enough is something what BATs should judge, and then ask the mapper to add an extra difficulty if the spread can be improved.

Assuming various possibilities, I wouldn't prefer a one size fits all rule.

iirc, stacks have NEVER been fine for the easiest diffs. Like, ever.

And low BPM sngs as in "how low?". Because an 80 BPM song with a 1/4 is the same as a 160 BPM sng with a 1/2... ...which is still very hard for the easiest diff.

And yeah, I meant short repeat slider with over one repeat.

they are fine.

1/2 160bpm is fine for normals (as easiest diff). pls, 1/1 spam is so laaaaaaame.

And while we're at it, don't make this a general rule as it doesn't make sense for other modes (or mania as far as I know). In case this is a guideline I'm fine with it, kinda.

The spread on each mode should be as per its feeling, that is if a map feels like an easy then it's an easy. Player output should always be primordial when evaluating difficulties. Also, star rating should always be an indicator and not an acquired value to evaluate a difficulties in other modes. For example, in taiko:
I made an easy 226 BPM map lasting for 1'00, which gave me 5.00 SR
I made a hard 179BPM map, with 2000+ note streams, which in total lasts 7'14. 5.04 SR.

The last portion should tell more concisely that the mapset should be accessible for every kind of player, implicitly for every level (Newcomer to thelewa tier)

The diff spread should be reasonable. If your Insane difficulty's star rating is over 4.5, it is recommended to include an Easy difficulty in your mapset, so that the gaps between the difficulties won't be too big. This way, you will make your mapset accessible for every player.

maybe more concise that way

Thanks for your opinions!

I forgot to say I am only talking about osu!-Standard, since I can't tell much about spreads on the other modes, sorry.

100% agreed.

Please also expand the wording by the following:
The highest difficulty must be fitting to the song, ergo it has to be appropriate. Mapping Experts to Moonlight Sonata isn't always a good idea either.

...or something similar. Really, not every song needs an Extra when it's especially slow or it doesn't fit in general. Because srsly

They're everywhere.

I don't agree with this one, it's basically banning all overmapping no matter if it fits or not. Don't get me wrong, in MOST cases it's bad but there are a few cases where overmapping is good. And Plus we all have our different views on what overmapping is. Obviously this should be considered more case by case because certain mappers (I don't want to mention any names) will get truly pissed if this happens.

Remember to be aware that it's not always the insane that causes problems in a map concerning diff spread :P *cough* https://osu.ppy.sh/s/102615 *cough*

To be honest, I think we don't need a new rule about this. I think BATs and player modders just need to actually look at spreads for once. Be like "Is this accessable to every player" instead of "Does this follow the arbitary rule of having an ENHIX spread"

There also needs to be definition past the star rating on what makes a good E/N/H. Right now it seems like

Insane/Extra:
Fun funfunfufnufnufnufn D:DDDD:DD:

Hard:
Insane diff with distance spacing and low SV

Normal:
uhhhhhhhhhhhhhhhhhhhhh

Easy:
nah

Which of course isn't very good. I don't know if we need an osu!academy video to help people understand or what, but it's important to give people the resources they need to make better spreads, instead of just getting mad at mappers for not having good enough spreads.

Having only insane difficulty over 4.5 stars doesn't always mean that the lowest diff would be "too hard" too - I often see maps with pretty hard insanes over 4.5 stars and acceptable enough Normal diffs. If only insane diff goes too hard and makes big gap, maybe it would be better to include second harder hard/second easier insane to cover it instead? And actually "too hard easiest diffs" can exist even in mapsets where insane goes rated below 4.5.

IMO, difficulty spread issues should be fixed case by case, and current rule already clearly says that difficulty spread should be well-designed.

I'll agree because I'm getting tired of telling people in my mods that their NHI mapsets can and should have an easy only to be ignored because they're too lazy to map another TV size diff.

I am having trouble trying to figure out what this guideline actually does. Are we trying to get a mapper to map a user defined easy diff or a diff below 1.5 stars. In other words, if I mapped a 1.9 star Easy diff, is that acceptable under this rule? Currently, what we define Easy diffs as something below 1.5 stars, but because the star system is not perfect, there are times where we can feel a 1.45 star Easy is still too difficult for a song for some people, regardless of the difficulty of the hardest diff.

Besides that, I have to agree with Kodora and CDFA that spreads should be investigated on a case by case basis if there is really an issue.

I never mentioned overmapping anywhere, diffs have to be appropriately paced, that's all.

And guys, remember that this is a guideline. Of course, sets need to be investigated case by case, and the Expert difficulty thing doesn't HAVE to be applied, but should genuinely be considered. We don't force anything upon mappers with this guideline, so it's fully acceptable.

Having this guideline would confuse new mappers a lot, and we should aim for clear and brief rules/guidelines.

I agree this should be handled case by case, not every 2 stars Normal is complex, but also there are a few that rounds 1.8-1.9 that are quite complex. This is regarding about the lowest difficulties.

Also I remark that we also should look for the gaps between difficulties, specially if they're >1.2 stars, this means it's likely too high and another difficulty should be done instead modifying the existent ones.

Basically what Kodora and CDFA said, but in from my point of view :p

I still think that depends on the song a lot. We should just stick to the fact that a spread should be reasonable; means the easiest diff shouldn't contain really complex stuff, as well as big gaps between normal / hard or hard / insane diffs (for example, you stick to the DS on hard with few jumps, and the insane is basically only jumps).

I personally dislike mapping easies for most songs, because they just don't cover the song like I want it to be covered. Beatskipping is a sad thing..

On the other side of things, some "insanes" shouldn't be called insanes when they're fast, jumpy, and streamy enough for the star rating to call them extras.

https://osu.ppy.sh/b/416215
https://osu.ppy.sh/s/175241
Both their hards are pretty hard but I still think the difficulty spread could have been better between hard and so-called "insane." The insanes here are extremely fast, lots of 1/2 and 1/4, deathstream and spaced stream in the second, etc. Definitely not an insane by anyone's definition.

This one's difficulty spread is flat out unbalanced.
https://osu.ppy.sh/b/127363&m=0

I would like to see more reasonable difficulty spreads on both ends, but here I'm mentioning the insane side because many players will be playing in this 4-5 star difficulty region, while it's relatively easy to improve out of the easy skill level.

Irrererere's post pretty much hits what we need on the nose. It's the mapping techniques employed in the difficulty that is going to be the biggest driver of difficulty, so even though you're going with a Normal for your easiest, you need to make sure that you don't use complex mapping techniques such as difficult rhythms, variable stacks, fast post-spinner notes/short spinners, etc.

I don't really see this guideline doing anything, unfortunately. Wording the ranking criteria to have more emphasis on having an even progression of difficulty would make things much easier to digest globally and will be easier to translate for non-English speakers.

Basically what Garven said about this rule's wording. It shouldn't be uuuh, "set in stone" by words since there are many occurences where it's very hard to respect the current RC (all mode wise). Just write something simple such as the spread must be balanced between diffs and then somehow add that the spread quality is left to BATs own discretion, implying that spreads should be treated case by case.

we always love to do a extrem diff for a song with a lively rhythm, but at the same time it's much harder to work on low diffs
to follow the rhythm, we could make low diff's star rate get a promotion
basic of this topic, i think in some song with high bpm, normal's star rate is unnecessary to lower than 2.25 absolutly if the map set has an Easy diff.make sure that Easy diff is lower than 1.75 star rate, still can create a well spread imo :)

Unfortunately SR is not perfect. Stop trying to make rules around something which barely gives a general idéal of a map's difficulty (despite the fact that the current SR is definitely betterave than the old one.)

well an uneven spread is definitely unacceptable imo, but having a spread thats slightly more spread out but still even should be acceptable. in any cases, you cannot expect any player to jump from a normal to hard in any map. i know i had to play the normals for several maps from easier ones to harder ones just so i can get to the point where i can pass an easier hard diff.

so tldr; even spreads, yes, but spreads should be allowed to be somewhat spread out as well.

The problem with the wording "Reasonable" in it is that being reasonable is always subjective and it will spark arguements, even if it is a guideline and not a rule. I will try to think up of better wording sometime later.

Just leave the decision to BATs and QATs. It'll still be subjective, but at least they have more or less the same definition of "reasonable".

Having too many difficulties on a long map is slightly annoying, however if used on a song below 2 minutes, this can be applicable.

The way that most maps should be is E/N/H/I, and I have been seeing some maps w/ E/N/H/I/I/X, putting to the risk of balancing, because of the amount of easy difficulties (E/N), and harder difficulties (H/I/I/X) isn't very balanced. Two easy difficulties and two harder difficulties is enough, but if you wanted to put in an Extra, then the spread isn't balanced, adding maybe an Advanced or a Beginner or both can fix that balance.

Don't try to make rules more complex than they already are. It's easier to allow a higher number of hard diffs than easy diffs within a set. Tbh as I see it, it's more like E/N/H are the "beginner" diffs, and "I/X(/X+)" the "expert diffs".

Let's not. Spreads tend to have more insane difficulties to provide more variety to the players in the skill level range who play it the most. Sure, there are hundreds of thousands of people who can only play normals and easies, but they won't play them many times, while the few tens of thousands who can play insanes for fun will retry over and over trying to pass/FC/DT FC for the pp or fun. That's why the presence of more insane diffs caters to this group of people.

I haven't read the whole thread, so I'm sorry if it's been mentioned, but possibly a guideline for how far apart two diffs in a spread can be? For example, that between any two adjecent difficulties, keep the SR difference lower than say 1.5 (just pulling some number). This way you can't have a 2.26 Hard and 5.24 Insane, and should cover the case of a 3 diff mapset's spread being too "wide".

We already have direct rule that difficulties should go in consecutive order; due to star rating being not 100% perfect i don't think that adding such limitations with numbers as rule would be really good idea. If jump between two diffs diifs feels to harsh it definitely will be noticed while modding - imo, would be better to leave it just as common sense thing.

I was talking about it as a guideline. I haven't looked much into how the new Star Rating rates difficulty, but from what people seem to think, it should be enough to make some rough guidelines as to how big of a difficulty gap between diffs should be. Obviously, as a guideline, it can be broken in the case where SR fails to rate maps appropriately, but it will give mappers and modders something to follow or consider. I mean, in most (or all) cases the 2.26 hard and 5.24 insane gap would be too big.

Before yesterday it never even once crossed my mind that people are treating the "consecutive diff order" as not skipping web icons for difficulties. This is beyond stupid. Who started treating it like this?

Let me show you something:




This is the range that decides which WEB ICONS are used depending on the star rating of any given map. This does, in most cases, NOT indicate a good diff spread.

See the small window to achieve a "Normal" rating? Some songs make it almost impossible to achieve the E N H spread while properly utilizing the respective gameplay elements in each difficulty bracket. You can end up with either E E H or E H H depending on the BPM of the song but the difficulties themselves are actually a perfect spread.

The quality of a diff spread can only be measured by checking gameplay elements used in each diff.
A nice even SR curve without huge jumps is also good to have. There have been guidelines for years and they have been consistent for the lower difficulties. I gathered most of the stuff that has been the "norm" but it is by no means complete. This only covers the lower spread as changes and new trends in mapping will steadily evolve the Insane and Extra tiers of beatmapping.

[Easy]
Generally following the baseline and the most distinctive features of a song. Leave some recovery times and use sliders to avoid monotonous 1/1 spam. Following the vocals or melody is a possibility. Consistent spacing is required to teach beginners the correlation between timing and distance.

Difficulty setup should include a low slider velocity, generous drain rate, low to medium hit accuracy, and a big circle size. Approach rate should be set to match the BPM and slider velocity of the map and allow enough time to plan the next move without cluttering the screen with too many hit objects.

Avoid stacked notes
Avoid overlapping notes
Avoid kick sliders



[Normal]
Generally following the most distinctive features of a song. Recovery times should be plenty but less than in the related Easy map. Use of 1/2 notes is encouraged as well as the developement of more interesting beat placements if the song allows it. Spacing should be mostly consistent to teach beginners the correlation between timing and distance.

Difficulty setup should use a low to medium slider velocity, medium drain rate, medium hit accuracy, and a big circle size that is the same or smaller than in the related Easy map. Approach rate should match the higher slider velocity and pacing of the map while leaving enough reaction and planning time without cluttering the screen.

Avoid triplets/streams (1/4 notes)
Avoid spacing inconsistencies



[Hard]
Following mostly "what you can hear". Try to capture the essence of the song and don't leave out too much. Interesting patterns and beat placements are encouraged along with jumps and short streams/triplets. If your mapset features a Normal and an Insane make sure your Hard map is a reasonable stepping stone between them.

Difficulty setup should include a BPM appropriate slider velocity that captures the pacing of the song. Use multiple slider velocities if needed. Drain rate and hit accuracy should balance the difficulty of your patterns and the frequency of streams and other 1/4 notes. Approach rate should match the BPM and slider velocity.

Avoid extremely long streams
Avoid full screen jump patterns






_________________________________________________________________________________________



Now that this is covered:

The "rule" will stay. The mis-interpretation will probably result in a rewording and the addition of a set of guidelines that will have to be worked on before they will be included.

We want to avoid spreads like N I I I. We also never intended to rely on web icons to evaluate the qualitiy of a diff spread. Depending on the BPM and nature of a song the SR completely fails to capture the actual difficulty of beginner or medium maps. Things like beat placement, readability, and usage of established gameplay elements will always be judged by the modding community and the BAT (or equivalent).

I don't think any new guidelines are needed. That's the responsibility or, say, modding routine for modders or BATs to check the difficulty spread. Trust yourself and judge it confidently.
Moreover, star rating is somehow incomplete and therefore not comprehensive enough to judge the real difficulty. Personally, it's totally unnecessary to make things complicated. If it's only a guideline, why do mappers need to follow it? They can still be lazy and things won't change in my opinion.

As huge CS hater i can't really agree with it, cuz CS4 easy and CS5 normals can be mapped pretty nicely and easy enough (CS5 was pretty good default CS size days back)

Overral really great guidelines, p3n! I believe all these can be added to wiki after discussion here - that would be really awesome guides for a new mappers! :)

This.

EDIT: I try to make my point a bit more detailed.

Providing another example of spread problem i faced : https://osu.ppy.sh/s/153776
The spread is perfect, but the star rating is inaccurate due to the high bpm. I think we're having problems with both the web icon and the star rating.

So additionally, I would like to add a bit more on the icon-spread/star-rating-spread thing. Since quite a lot of unnecessary unqualifications happened these days,

The difficulties in the mapset must be in a consecutive order.
a consecutive order does not always mean a consecutive web-icon-spread, please see the 4-diff spread example below,

it's a perfect spread from the SR side. But it's a bad spread according to the web icon(E H I X).
That's totally weird, isn't it? Actually we will never know if the spread is good or bad until we actually check through the patterns in the diffs.

Mentioning this with p3n's point above and fycho's point below as well. Most Insane diffs are over 4.5 stars nowadays(especially on high bpm songs, 170~). As far as i know, the new star rating system values a diff depends on the physical difficulty for players to achieve it. So the SR varies with different bpm. Two Hard diffs containing exactly the same objects in 150 bpm and 220 bpm will have totally different star rating. While it does not mean the pattern usage is anywhere different. I don't think star rating is perfect atm.

Then, is it really necessary to have everything with 4 diffs or even more according to star rating? I will never know.

But yeah, if we're going to word a guideline. We must have a specific description about the case(4.5 in this case). With the star rating being inaccurate and not reliable. We can't really word anything depends on a not reliable source. Plus if it's a guideline instead of a rule, then it can't force anyone to do anything about the spread. Guideline does not lead to unrankable stuff so sadly they're quite powerless.

tl;dr:
I believe spread can be manually checked and judged by modding community and BATs from case to case. Do not be too relying on star rating. They're not perfect. Personally, I do not think we need such guideline.

I almostly agree p3n's post, and I don't think there needs any new guideline, also the "icon-spread" shouldn't be taken considerated when ranking/unranking a map.

Star rating is not completed atm which can't be used as reference imo, for example this map, https://osu.ppy.sh/s/97925, spread was totally fine at the beginning, also charles is quite sure of it, constant jumps of usage in insane diff makes an "EX" icon, and triplets/jumps in hard made spread fine too.
However, recently I was told to change some 1/2 sliders to constant 1/2 circles to make hard a "Insane icon" to avoid being unranked. This sounds even silly.

BATs/QATs should judge spread case by case, not relying star rating.

so basically, unranks like this one: https://osu.ppy.sh/forum/p/3381966 were pointless?

Looks like that, Natsu.
I personally also think we shouldn't judge according to the Icons but as remember we were told (like this unqualify shows) not to qualify Maps that don't have a consecutive Spread (according to thethe amount of Stars in the RC).
Also about two weeks ago I've asked a QAT about it and he also said that a Gap within the Icons is unrankable.
But yeah, completely agree on what Oracle said. Spread is a case by case thing that also depends on BPM and overall playability that the SR probably doesn't get accurately.
