Rating jumps make old chess habits look like current ones
A 200-point climb rewrites which “usual move” the sample should trust. Mix the climb with this month and the report will scold a player you are not.
Prefer the current time control and the last few months unless you are specifically studying an old repertoire. Refresh the import after a real rating move.
Baselines should be recent
Chessigma compares you to you. If “you” is half a weaker account, the usual move is the old move.
Arena months, a new opening kick, and a switch from blitz to rapid all deserve a fresh cut of games.
What the 200-game cap cannot fix
If all 200 games are still from the climb, wait. Do not force a repertoire change on a transitional sample.
Frequently asked questions
Should I import every game I have?
No. Current clock and recent months first.
Will auto-refresh drop old games?
It keeps the newest block under the cap.
