Use the video provided by WGT. and I made these corrections on my post.
THANKS FOR BRINGING THIS TO MY ATTENTION.
ALL input is welcome, with respect to the issue of trying to help those who do not know how to calculate putts.
5. New hole distance is 10 feet + (-6.5) or 10 - 6.5 = 3.3 feet to the hole.(NEW DISTANCE)
CORRECTION
New Hole distance formula:
1. Actual Hole distance = 10 feet.
2. Fall = (-5) inches
3. Adjustment is (-5) inches x 1.3 = -6.5 feet
4. New Hole Distance = 10 + (-6.5) = 3.5 feet.
NOW, IN THIS FORMULA I INADVERTENTLY USED THE CORRECTION FOR FAST SPEED GREEN WHICH IS:
5 . 3.5 X 0.95 = 3.3 or 13%
6 FOR VERY FAST GREEN : 3.5 X 0.85 = 3.0 feet or 11.9%
7. FOR TOURNAMENT GREEN 3.5 X 0.75 = 2.6 FEET OR 10.5%
8 FOR STANDARD SPEED (SLOW) = 3.5 FEET OR 14%
These formulas work consistently for me, if you have a better way, please advise.
