When you analyze chess game with the engine on the site and lets say you make bad move -2.00. Below it says Blunder or mistake etc. Best move was Nxf7.. Ok, but tell me how much this improve game in terms of numbers.. 0.00 . +1.30.. +2.00 ..
Positive means that the position is good for white, while negative means that the position is good for black. A highly negative position can mean either that white made an idiotic blunder, or that black made a brilliant move -- just understand that the position is being scored, not the move itself per se.
Not always. Also, I did not ask what + or - means. +0.30 means nothing. It's equal. And specially in Bullet -2.00 or -3.00 can turn in +#3 mate in just 1 wrong move from black.
So to show what i mean.

22. Fxg6 -2.1 ... hxg6 +1.4 It's blacks blunder. Best move fxg6. Ok, tell me after this suggested move how much is the score. How danger engines think is the position.
23. Qh4 -4.70 Blunder.. Best move Rxf7 and the position i think is +1.5 for white but this is not visible, etc. The engine does not say that, only moves without evaluation.... I am asking that , to add this 1.5 next to best move. It's 5 min work or less probably...

He suggests that the evaluation of the (dis)advantage should also be stated in the calculated variation of the engine.
the best move score is at opponents previous move here -2.1
