Well it varies... Depends on how much time the Ai needs for understanding your true skill level to compare you with your peers, measure your accuracy etc. but i would say try to hit 100 games for accurate results

Hello,

Lichess Tutor is a great tool that works very well.
I received my detailed analysis in less than 2 minutes, and it’s truly insightful!
However, in my opinion—and to avoid potentially hurting anyone’s feelings—it might be better to steer clear of overly negative terms like "is much worse than your peers," replacing it with something like "is clearly inferior to your peers." Also, perhaps consider moving away from the color red, which can feel a bit too aggressive (maybe use purple instead, which is softer).
Otherwise, everything is perfect! :)
