Re: If you haven't already, try this in rough!

  You're in the rough. 40% to 50% rough.

  How much more club do you need for the distance of the shot because of the rough?

  Example - You're 50 yards from the green in 40% to 50% rough. You want to play for some roll after landing on the green and leave the backspin indicator where the auto caddy puts it.

  Use the 40% value - 40% of 50 yards is 20 yards. Use the club that will normally hit the ball 70 yards (50 yards + 40% (20 yards) = 70 yards.

  If you want to play for less less roll and move the spin indicater to or near the bottom of the ball -  use 50% - 50 + 25 = 75 yards

  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.
