I'm not sure I understand the new category rankings. Why would Category ranks for Evo change when a solo-only puzzle expires? There have been no expired Evo puzzles for several days (I think).

The explanation says best 40 out of 50 puzzles. Is it affected by non-evo puzzles as well? For the category rankings to make sense, a evo rank shouldn't be affected by a solo-only puzzle. Otherwise, it isn't truly based on your Evo performance at all.

Also, are the category rankings subject to a sliding "time window"? A couple of other people in chat were confused about these issues as well.

Sometimes the points and rankings are changing even without a puzzle expiring.

So I think there is a sliding time window. I assume it is about 4 month.

Global soloist rank and score are based on a sliding time window and on all puzzles.
Category rankings are computed according to the specifications. See the Categories tab.
No time sliding window and scores and rankings only change when a puzzle closes (or exception: when a puzzle was wrongly placed in a categorie and that is corrected).
It can take up to a day before categorie scores are updated I think.

I'll assume there hasn't been time to look into this yet, so I'll add an additional request.

Could someone please verify that when puzzles are canceled/retracted/reissued that the defective ones don't count as one of "the last xx puzzles" and such? The programmers probably already thought of that, but being one myself, it doesn't hurt to ask.
