So what do you use for 30% or less? Also on "deep" sand or rough(40%-50%) like BP I find when I add say 40% more power that many times I'm too long on the shot. Thanks for the info.
30-40%, see above. Punch shots lose less distance than indicated, full shots from bunker do.
Below 30% you may try any club from the rough and at least the irons from the bunkers. Shots from rough suffer less than indicated, short iron shots may keep their distance.
From 50+% rough, it's hoping for the best and play out short distance to FW.
Mulch is a special ground (e.g. at KIA) - add the extra %% power x2 / x3 and hope for the best.
Common to all %% lies is less influence of spin.
