With a little cheating kiddie running rampant today, I noticed something.

Take a quick look at these scores:



Is there a specific reason why the pp values are so ridiculously low? Equivalently difficult scores in any of the other modes would be worth at least 1k pp each, probably way more (judging from the huge scaling at the top level, they might even be worth multiple thousands of pp).

I made a difficulty calculation algorithm for taiko maps (based on the rhythm complexity algorithm I was working on for osu!, but also taking strain into account; the value represents both the strain and the rhythm-pattern complexity, since checking the algorithm by playing maps is less straightforward if the 2 values are separated. I was testing with this mode since it is the simplest one to analize); the scale of the values is made similar to the scale used in the current star difficulty (Tom Stars).

Finishers are considered the same as regular notes for patterns (since hitting them with both keys is optional). Drumrolls aren't considered in the algorithm at all.

The algorithm doesn't include factors that affect reading difficulty (such as scrolling speed, scrolling speed changes, finishers blocking other notes).

Here are some results (for most ranked taiko maps):
https://www.dropbox.com/s/e4l17ig7vtwat ... .xlsx?dl=1

a) What do you think about those results in general?

b) An earlier version of the algorithm used to detect color-inversed repeated patterns (for example, ddkkd kkddk), but I removed that detection (making the algorithm consider both 5-note patterns as completely different) since when I was playing I noticed that color-inversed repetitions confused me more than helped (I tended to play the 2nd pattern the same as the first instead of inverted), but that could have been only because I am pretty bad at reading Taiko (in osu!mania, the equivalent concept of mirroring patterns actually makes thing easier for me). Should I re-add color-inversed pattern detection?

c) Some maps that players have said to be pretty hard, but are rated considerably lower in this algorithm compared to the current Star Difficulty, are Shinsekai and Taiko Time. They are rated lower in this algorithm mainly because the algorithm finds many long repeated patterns:
In Shinsekai, the algorithm finds many patterns that are 8-notes long or higher next to each other (up to 16-notes long).
Should I make the algorithm less sensitive to long patterns repetitions (longer than the ones the average person can keep in their short term memory)? If I did, then people who are good at memorizing patterns in their long term memory would have an extra advantage. On the other hand, if a pattern is long (and not composed of sub-patterns), there is a higher chance the player doesn't have any experience playing that specific pattern.

Awesome! If the response to your system is generally better than to the current system in place I'd love to use your system (or at least incorporate it in some way - there need to be certain guarantees fulfilled). That is if you'd be willing to share it of course.

Anjuu Tianlan is above Anjuu Zhuhong now -514

What would be nice is to have it tested with non-ranked maps. I can provide you some example maps that are deemed overrated / underrated by people.


small edit : wtf how come Anjuu Kantan DT is rated that much

Since when did HD give not enough pp? I don't understand that buff.

I believe somewhere along the line the intent was to buff hidden on slow songs not fast ones
it seems to have gone wrong, i'd just wait it out.

can't even manage to fetch SV and BPM at all? kinda odd, considering they're a bit like AR (not completely the same) so yeah. x_x

While I don't like the current state of lower difficulties for taiko either. It is better to make easier diffs that can be universally accepted, rather than what YOU think provides the proper challenge for a noobie. Easy/Normal serve the purpose of basic rhythms and learning the difference in color. That is it. There isn't really a reason for them to be more complex than they already are. Muzukashii serves as a good platform for applying your rhythm and reading abilities learned from Kantan/Futsuu into full fledged rhythms.

I used to think how you do, so I know where you are coming from. But I do agree that the star rating scale for kantan/futsuu is ridiculous. You can't even add a few simple 1/2 patterns without the star rating skyrocketing.
