Are "excellent" move really stronger than "best" move?

Hello guys! I was playing with a friend and by looking at the analysis I noticed something weird. Here's the image:


The "excellent" move bring the black to -10, while the "best" move to -57. That means that the "best" move is roughly 6 times stronger than the "excellent" one, but I have thought that an "excellent" move is stronger than a "best" one...can someone please clarify this concept to me? What am I missing?

Thanks!

I don't know the definition level for here, but the best move is going to be better than any other move, from a evaluation standpoint.

An Excellent move would be one that does not change the evaluation too much and is still a good move for that player.

Blunder, Mistake, Inaccuraccy

Good, Excellent, Best, Brilliant

around the end a brilliant move was played by me but what's the best move or even how is it brilliant seems obvious 

I think it says brilliant because it's the only move and any other move apart from f3 leads to a draw. So I think it's the best move and also a brilliant move at the same time. Also well done for winning @Sleepingpuppy

Thanks for the replies guys, I overlooked the rank of the evaluations, now it's much clearer!

Nothing can be better than best, by definition.

Yes, I agree, that is what would make a move brilliant. By that criterion, I wouldn't call ...f3 a brilliant move. It was pretty obvious. If black had played any other move, the engine would have called it a blunder or missed win.

The best move is by definition the strongest move in the position.

A brilliant move is a best move that is also hard to find.

An excellent move is a strong move that is slightly behind the best.

Exactly and precisely. Best explanation given.

Thank you!!!

Here is a blitz game that i've recently played...

37. R1f7+ was considered a brilliant move... after move 36 it is clearly an  obvious move.. So is a brilliant move a hard move to find or a key move from a hard sequence to find ???

Seems like semantics. My uninformed opinion is a best move exists at every step of the game, a move chosen having a dynamic shift and not merely procedural would be an excellent move. 

Humans have a lot of weird ways to describe similar things. That's why we have wars and stuff. It just doesn't mean the same when you say 'horrible' and 'disgusting'. Connotations and Denotations are the reason there are wars. STOP LEARNING GRAMMAR NOW!

I saw this in Gotham chess but I don't understand how he did this

Best > excellent
