suggestion for an analysis tool

I play a lot of 1-minute games. But I also play some 3-minute games and some 5 minute games. I used to play a lot of 10 and 15 minute games but not anymore.

I'm pretty sure that I'm better playing fast, and I think I play better against higher ranked opponents.

It would be nice if in My overall game analysis I could look at only my games of a certain length (like start time under 2 minutes) or against players of a certain ranking. That might help show if I'm actually better at speed chess.

If you look at your Chess Insights e.g.

lichess.org/insights/tailuge/acpl/variant

It does give you a breakdown of ACPL by bullet, blitz and rapid - maybe not exactly when you want but its close.

I also have this

tailuge.github.io/mistake-o-tron/index.html

which allows you to look at your recent mistakes and filter by time control.

Ah thanks for the suggestions, @tailuge! I should have added that I'm only playing 960 games. So within 960 there doesn't seem to be any differentiating between different speeds within that.
Cheers!
