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

Best > excellent

According to their definitions, a Great move is always a Best move where the so-called Great move is also necessary to either save a game or to win a game. Logically, a Brilliant move isn't always a Best move. Their Best move is what it says ... at least, according to the engine analysis. Very occasionally, the engine is wrong. I remember in one of my Daily games, the engine made several wrong assessments and on one occasion it would have missed the win with its so-called best move, which only drew. That game was almost without tactics and extremely positional ... I was playing black against a Stonewall Attack.

Good moves are supposedly moves you can get away with but that isn't really so, since it seems to be programmed to find good moves and occasionally will come up with a Good move which loses. Excellent moves don't normally do that; and they're the engines next-best moves to their Best moves. Occasionally, an Excellent move or a Good move is better than their best move, in reality. This can be checked by taking the analysis forward by about three or four moves. The analysis learns, so it's partially AI and when it revisits that position, it may not make the same mistake, although I think the learning is only in the context of a specific game. I forget what they call poor moves but also, a move it thinks is poor can be excellent in reality. It's a work in progress, I suppose.

Chess.com is actually doing a great disservice to players by this whole nonsensical "Game review" stuff. This topic clearly shows the confusion it causes in everyone's mind.

It would me much-much better to instead teach new players how to use the engine and how to interpret what you see in engine analysis.

Completely agree but they've identified it as something which a majority of people are willing to pay for a Diamond membership to get. It's extremely annoying and there ought to be a button to turn it off, so it's invisible. Then there'd be less useless clutter.

It's ok if you need some laughs.

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!

This is not true. Also, it is complete nonsense.

Excellent moves are good moves that are preferred by the engine at the 2nd priority. They are almost equal to the best moves but not better than the best moves as the best moves are the moves preferred by the engine at the first priority.

I have yet to get a "Brilliant" and I still don't know how to get them. I've noticed when I get Great Moves", it's because what I did was the first move from the "show moves" either from putting myself in a good position or the bot made a blunder. But how do I do a brilliant move, like I would imagen that the popular 4-move checkmate thing would be a brilliant, but It's not, it isn't even a "Great Move".

Brilliant moves are ones that sacrifice material or allow material to be captured and are good or best. There are some other things that can also influence it
