6 years ago There's nothing unfair and it's not a bug. Solving a kata rewards the same amount of internal score regardless of the user's rank. It's just harder to make progress once you reach higher ranks. Also, your example progress % doesn't seem correct.
The rank progress is calculated like the following:
(score - rank_score[rank])/(rank_score[rank + 1] - rank_score[rank])where
scoreis the internal progress score of the user- can be found in

rank_score[rank]is the score required to reachrank- max

For the second part, we should have a separate issue to discuss or continue in #35. I think Jake wants to make dan levels distinct rather than continuations of the kyu ranks.

Hi,
2 things here:
1) rank progress when being 1 dan:
I noticed that the % of progress given when solving kata when you're already 1 dan suffers what could be considered as a bug. The normal observed pattern is the following for every "kyu" rank user:
A user being at the rank "N kyu":
Though, being 1 dan and solving a 1 kyu, you get only something around 1% (impossible to know exactly for now, not being over 90% in 1 dan level x) ). That's due to the rank 0 kyu that doesn't exists, I'd bet. But that feels unfair to any dan user, doesn't it? ;p
2) 1 dan level kata:
Well, it's about time, I believe, to open that field. There are already several katas that match what jhoffner/Voile talked about in #35. To those already quoted there, one can now add, I guess:
Even if still in beta, it's almost a shame to assign only 1 kyu to those, imo.
