I also get some very strange results from analysis. "Good" move rating for moving a piece so it is en prise.
Analysis: Difference between Best, Excellent and Good moves

Well I think moving a piece where it can be taken and where there is no compensation should be a blunder. I'm not talking about a sacrifice or anything. See this example. Black allows his rook to be taken and it isn't criticised as even a bad move. Sure enough Bxe6 would be the best move but Rb7 is a disasterous move dropping eight points in total. Worst of all the right had says Rb7 is "good," when it clearly isn't.

That is bizarre. I found that game and got the same result on that move.

@hedgehog, I reported the misanalysis in your game separately.

Hi,
Is there a description for example when a move is classified as excellent vs. good?
For example an Excellent move is between 0.01 and 0.50 worse than the best move, good is between 0,50 and 1.00 from the best move and etc.
Unfortunately, sometimes the Analysis says that a move is excellent, although it is way worse than the best.
Best Regards,
Yavor
