On down hill putts - hit the exact distance of the result.
On uphill putts add a foot to your computation. (You really don't want to leave an up hill putt short).
parameters:
E = elevation change (+) for uphill (-) for downhill in INCHES
D = Actual Distance to hole in FEET.
THE UPHILL PUTT= {[(+ E ) /(12* D )] * M(CSG, or TSG, or VFG) + B(CSG, or TSG, or VFG) } x D + 1.0 Ft
THE DOWNHILL PUTT = {[(- E )/ (12* D )] * M(CSG, or TSG, or VFG) + B(CSG, or TSG, or VFG) } x D
Take the result(s) divide by the appropriate meter ( for my Odyssey putter meters are 15,30, 60 ,100, 150) and voila you have how hard to hit it.
I have plugged there formulas into an excel spreadsheet that I have open while I play - one page for Championship Speed Greens, another for Tournament Speed greens, and another for Very Fast Greens. All that I type in is the Distance to pin and the elevation change.
I can complete the calculations in about 3 seconds. It takes another 20+ seconds to read the break. If you have a putt with TWO components - one uphill, then one down hill, calculate the components separately then add them together.
For Very Fast Greens M = 9.3966 and B = 0.845
For an uphill putt:
HIT = Dist. to Pin in feet *(9.3966 * (elevation change in inches/Distance to pin in feet *12) + 0.845) + 1.0 Ft.
For a down hill putt:
HIT = Dist. to Pin in feet *(9.3966 * (-1*elevation change in inches/Distance to pin in feet *12) + 0.845)
let me know how it works out - practice at Beth Page Black as the greens are very flat.
If you want to learn the M,s and the B's for Tournament, and Championship greens, challenge me to a stroke play game and you can see for yourself.
