I think that it is possible that the same evaluation change that is productive at long time control is counter productive at blitz. It does not mean that testing at short time control to test evaluation changes is not useful but if you want to be sure that the new version is better and you care mainly about long time control then you need to test in long time control. I suspect for example that a small reduction of the evaluation of pawns may be productive at long time control and counter productive at blitz. The reason is that piece is usually better than 3 pawns in the middle game but at blitz you may not have enough time to find the plan how to use it espacially when the side with the pawn has another positional advantage that is not enough to compensate for the piece when at long time control you may find the right plan because of searching deeper. The right plan for the side with the pawns is more simple:push the pawns forward It means that program will have less problem to find the right plan even at blitz. I do not know if this theory is correct but it is possible that another theory for another evaluation term is correct. Uri
