is 94,5 good for an 880 in a 17 move game?
that's a GM average but in a match is okay to have that accuracy , if you keep it with that elo, in 9 games your account gonna get banned 100%
( accuracy% vs rating# ) is NOT one of the criteria the Cheat Detection Team uses for detecting cheaters. At most, it might draw their attemtion to a particular account. By itself and uncorroborated, it would NEVER trigger a ban.
Ofc don't but u can't have low ratting having over 90 accuracy in the most of your matches, believe me
If I had to give a number, though, I'd say 75% is good for me.
