Wait... What???
great move is not the best move?

Some clarification if you can't understand OP
Great move means "the only good move"
Best move means the "best move"

The best move might mean faster win than the great move, it's possible that if you make the "best move" it'll also appear as great.

it's just using best and great as different things; while Re2 is a good move, c3 is a better move.
In other words it is technically incorrect to say 'great' as better than 'best' great finds are higher in the move rank that best moves.

No...? The best move results in -12.1 favoring black, and the great move results in -11.2
Based on the score alone, it can be assumed that the best move is also a great/brilliant move, and that the great move was simply slower.

Yes, I know that, but if the "only good move" is not the "best move" then how is it the only good move if there is a better move?
Edit: I also tried going to a separate analysis and playing Re2 and it said "Re2 is best" "c3 is an alternative"

Previously, that classification was also the best move and it altered the course of the game. Now the tool-tip emphasizes that latter part but in most cases it's still probably the best move or close enough in evaluation.
