Yes, that it is it. The margin to exit can be different at various
points in the eval. It also helps if you avoid cases where there
are potentially large eval terms you have not calculated yet. E.g.
I have a large bonus for pawn races where one side appears to win:
if the pawn race code might be triggered I disable lazy eval in the
sections of the code before the pawn race calculation.
