gerryniswonger:The yardages listed for pitch shots are significantly shorter than they they read.
I don't quite understand what you mean here, Gerry. Are your pitches stopping before they get to the yardage the spec says it should go? This would be really unusual because pitches roll after landing, usually much longer than what it's rated at (on flat landings.) Even with premium balls and backspin you get some rollout.
I don't chart the actual difference out of the different roughs but will subtract a couple of yards for 30-40 and about 4 or so for 40-50. Pitches out of rough and sand are hard to stop so you have to play the roll which is what makes your question a little puzzling.
50-60 rough is a punch for me, not even sure if a pitch works
