Yes but my point is that if you have already evaluation of +3 then it is better not to sacrifice pieces for pawn endgame with unstoppable pawn when you cannot be sure that the opponent does not queen first. Personally I was very careful in adding bonus for unstoppable passed pawn in movei and I even do not evaluate unstoppable passed pawns in case that the opponent has some open pawn that is more advanced or even the advanced to the same rank. I may decide to improve it but after all evaluarion of pawn endgames is not very important for playing strength. I use the evaluation as one of the factors to decide about pruning and big bonus for cases that I am not sure is dangerous because it means that it is also harder to find things by search because lines get pruned and I may need another ply to see the danger of transition to pawn endgame.
