golds its just too complicated to comprehend if he made a programme it would be better :P
I agree golds is complicated, but on the mark, it takes into account dot speed and distance.
Here's a method I started with a while ago, it was an excel sheet I tweaked from Spammage, he gets full credit here for getting me thinking about the math and not me.
First break down the dot speeds into Vslow, slow, Medium, fast and vfast. 5,4,3,2,1 in that order.
Assign the following factors to above call them dot speed factors, 1= 3, 2 = 2, 3 = 1.5, 4 = 1.25 and 5 =.75
Elevation factor Up = 36 down = 24 level equals 30
Learn excel folks:
(Distance without elevation X dot speed factor) / (elevation)
IE.......:
8 foot putt down hill vfast dots = 1 full box to aim (8 X 3 =24) 24/24 = 1
Aim 1 full box
Lets try 25 feet uphill with slow dots. (25 X 1.25 =31) (31 / 36 = .87) .87% of a box to aim.
Just a start folks, you can fine tune the factors and get far more precise. but just to show you there is a potential math to this madness.
If the math comes out at some other number its how many boxs, or grids to aim.
Simple, but don't expect to be dead eye dick with it, you need to know in order to be super accurate and perfect, every dot must be measured precisely to the 10th of a second, and the putt must be executed at a precise distance. Above will get you close and in lots though. But who wants to do that much precise math, not me certainly.
But if you really want to get good, you need to take the above and practice and tweak the crap out of it.
How to tweak the crap out of it? Well for starters add another factor for champ greens say 1.2 and multiply the result by 1.2 or .80 for slow greens.
It's no easy fix here folks, there are just so so many factors that go into making any putt.
Practice above and figure out the dot speeds, the key, IMHO, lies in the dot speed, and remains elusive to me to this day.
