Analysis feature request: Cutoff summary after a threshold

I really like the analysis feature, it was the reason I started playing here (and becoming a monthly donor). I have a suggestion for the summary part. After a certain point it is obvious that one player will win, maybe at -10 or so. If whatever threshold is passed, and not crossed again until the end of the game (and the game is won by the player in the lead) I think the game can be considered to be over at that point. It does not matter much if one of the players makes a suboptimal move.

When using analysis the summary would be improved if mistakes and blunders after the threshold is passed are ignored. It is the play leading up to the threshold that is interesting, but the mistakes after that point (due to time pressure often) often makes the summary meaningless.

The threshold could be illustrated with a vertical line, showing that the engine considers the game over by this point. If the threshold is configurable by players then you could adjust according to your skill (or have automatic adjustment based on rating? with manual override?).
