Would been a good idea about considering stream lenght by time instead amount of circles at all. Also both cases of very long streams and really fast stacks (355 bpm likely seen at xi - Breakthrough Atmosphere +DT because streams of 1/6 at 237 bpm) are both cases underrated. Seems that the meta for pp is finding a map full of "streams" 5-9 circles frequently, not complicated stream shape (mainly lineally and fluided ones) with higher spacing between circle and OD equal or over to OD8. Maps with streams of +30 circles and over 4 seconds of tapping aren't that seen in people's best performance, mainly because they're highly underrated compared to easier maps that can give more pp for less effort.

I find confusing that on some cases a 5.1 stars map likely Tristam & Braken - Frame of Mind [Chill] can give more pp than maps with 5.48 stars likely Shounen Radio - neu [Gold]...

Facts to consider
1.- Shounen radio has 821 elements, Tristam has 1042 elements
2.- Shounen radio is OD7, Tristam is OD8
3.- Tristam is much more consistent than Shounen radio is
4.- General ranking on top 50's talks by itself.
Personal tought: Tristam [Chill] is being highly farmed because it gives a way too much pp from accuracy value, instead shounen radio [gold] is avoided due it needs strong constancy at fingers on some parts and being massively underewarded because it's worth as very low accuracy on pp.

What I want to highlight from this?
1.- There should been a star system from "average star level" and "hardest star level", this would allow people to find maps to properly train constancy or instead going ahead for maps with high peaks of difficulty.
2.- General pp obtained from a map SHOULD be based on "average star level" and if this is worked finely, it should been balanced on both cases that requires or constancy or a nuke of skill on atleast a single part. This would take lots of effort, but looks promising.
3.- Accuracy is being overrated (mainly OD+8 with many circles). This makes people to avoid maps that they can't do with really good accuracy and instead they go for free accuracy = free pp maps. Needed of more tries to FC 95.50% Shounen Radio [gold] than to FC Tristam Frame of Mind [Chill] with 98.02% accuracy.

Preffered to not extend on too many topics at the same time, just mentioning one and describing another clearly.

Good theory, could be the reason yeah.

Pretty interested for the results. Also, the pp vs. star rating thing DroidBass mentioned is legit. Some star ratings seem really off, and it still feels counterintuitive to me that a map of a certain SR would give less pp than a map of lower SR than the first.

This can happen often due to accuracy rating due to OD, length, etc, i'm trying to minimise that effect here though

This is probably the reason. In the graph you can see how the amount of BPM difference increases between each of these "steps". Those breakpoints are where the 32 note stream starts being completely contained within one less of these intervals.

If you'd want to compare the difficulties of such streams I suggest you make a map at least 30 seconds long where you just repeat those streams with a short break inbetween. Sadly there could still be aliasing artifacts when the BPM and the time interval share common divisors, but they shouldn't be as bad.

The sudden knack at 300 BPM is by the way currently caused by a hard cap avoiding singularities in maps putting some hitobjects 1ms or even 0ms apart. I should probably make that higher now that some people actually start to pull off 300bpm scores.

you forgot 1 major thing.
tristam has 923 circles
shounen radio has 652 circles
sliders arent considered for acc, only for beatmap length.

so not only is tristam a higher od, it also has almost 300 circles more.
when aim/speed/acc get divided you will see that tristam most likely gives 30-40pp more in the acc part compared to shounen radio. while shounen radio will give more in the combined aim/speed part.

unfortunately pp cant tell how hard a map actually is to acc, it purely looks at od and amount of circles for that part afaik.
Nyxa
IIRC that's the main reason why HR often feels undervalued. If the map doesn't score high in aim or speed but is still hard to acc (like marathons) it won't give any decent pp below 99%
Vuelo Eluko
also because most people don't have high acc.

Thanks for the explanation, makes perfect sense now

This, the reward curve for HR is incredibly steep so the only way it rewards you is if you get 99+% acc or if you're playing a 3+ minute map.
Nyxa
Even 6 minute maps give little under 98.5% unless it's a map that's hard to FC.
ZenithPhantasm
I feel like acc pp scales too exponentially. It should be more gradual imo 8-)
And I feel like Hidden aim pp should be 0 because its basically preference.

Well, no.
While it's true that maps can become easier to read with Hidden it's still a lot harder to maintain combo. Hidden is clearly my mostplayed mod and the amount of shitmisses I get with hidden compared to nomod on maps i can play very comfortably(99%+ nomod) is immense. I think the difference could get smaller once I get better but I don't think you'll ever be equally consistent when using hidden.
Nyxa
Playing with HD is like synchronised swimming. Either you love the shit out of it or it absolutely disgusts you. I'm in the latter group.
ZenithPhantasm
I still feel like Hidden gives too much bonus pp.
B1rd
It only gives too much pp at high AR. ar9 is where hidden give the proper amount of pp. And yes it does make things harder to read.

Whether it makes things harder is somewhat subjective. Ik people who cant go without slapping on HD mod.
B1rd
It's not very subjective. It makes the object disappear before you have to hit it, so you have to memorise the location, and it makes it much harder to see stacked objects. This isn't subjective. There are very few people who can read HD better at AR9 who have not almost solely played HD and are not used to nomod.

You should know that this is an illness. They do it because they got so used to it that they started sucking when playing with approach circles. It's a similar phenomen to the "cant-play-below AR9.67"-people.
