Always map without apparel for all your clubs. As far as variances between practice and actual greens a number of variables come into play, spin, type of shot, and green speed being three of the most influential. I believe the best approach is to map your wedges as you have done and take them for a test drive on various greens. Your mapping will tell you how hard to hit the ball. Then try pitches, flops, chips, punches and look at the actual result. After some practice you will begin to see a pattern and that turns into game finesse. You know your mapping says hit 95%, but that has a tendency to go a yard or two long, I’ll hit 94% instead; my short pitches roll long, maybe I should use more backspin. With practice you will have the wedges honed it.
BTW, I don’t know if there is apparel that affects the performance of wedges.
