AFAIS this calculus doesn't work too well:
Wedges will shoot longer than that from any %% surface,
long clubs will shoot considerably shorter.
Courses act differently on the shots.
Examples with Satins and G20s:
Had a 60 yds shot from 40% rough at Merion, took the 77 yds wedge to 12 feet - 25% reduction only.
From 170 yds out, e.g. on CCC, I opt for a punch, pull the meter a wee bit more and hope for fairway for the bump&roll from 90 yds carry length. A full shot would stay way short. At Merion, I'd take my pill and wedge out probably.
