This is so important, and people who watch games with engine eval or with commentators who use it don't realise it at all. Often in a chess game you're looking at a position and going "am I even ahead here?"...and when I do an analysis of my own games I'll often find that my own sense of the position doesn't at all agree with an engine evaluation. Clearly the situation is going to be much harder at the elite level where the edges are smaller and doubly so in this particular world championship where the positions were generally extremely complex and double-edged.
