Some mistakes or innacuracies are not reported :example given :
lichess.org/fT6NG35s/black#37Which move should be reported, for example?
19...Qd5?! .a difference of 2 points in evaluation.Maybe it is a percentile compared to best move : example -25% of the evaluation of the best move then it is reported?this would explain...
It's true that Qxa2 is slightly better than Qd5, although either way White is down a piece and a position.
