Why do the returned ratings vary by .5 when using pavil depth vs. pavil angle(info pulled from a Sarin Report and inputed into the cut advisor for the same D).Is this why you get only 5 tries? I would think you need total depth and girdle if % where used on pavil.PS Five tries ain't enuff. I found a good performer, on the cut advis, but was sold before I could purchase. I'm still looking but won't have the cut advis as a helping tool.
