pdb1: alosso: Second, please refer to scores as full numbers, not +-Par to avoid ambiguity.
. But it is ambiguous . Just like so many other things in life . A -6 to move my average .01 and nothing more will count .
-6 is ambiguous to the point of futility. It may be 72-6=66 which probably wouldn't affect your average at all, or it may be 34-6=28, doubled to 56, a fabulous score with a "huge" impact of more than .01, definitely visible in the average.
