  And big thanks to you, Dave, for your kind words.

  All the best!

  I was just playing around with this the other day without doing the math and came up only 2 inches from the hole. I was 6.9 feet away from the hole with a slight elevation between me and the hole. I brought the blue flag directly over the line with the double white dots and aimed my putt there. I was amazed how the ball knew exactly where to go in an "S" curve to the hole. A little more power and it would have dropped in. Will have to follow up on this formula since it seems to work very much.

  Thanks

  Joe

  G0LD:

  the number of sloping inches is added to the stated distance (measured in feet) or subtracted from it, depending on whether the slope is upwards or downwards. In my above example, we subtract 6 from 13, and obtain 7 feet as an adjusted distance.

  Hi G0LD,

  I was trying to follow your formula but was a bit confused by this statement.  I wonder if you could plug in the adjustment for tournament greens to your example above:

  G0LD:

  You must determine the fraction that the slope (6 inches) and the stated distance (13 feet) together represent: 6/13 = 1/2.16. You then multiply 43.43 by this fraction (43.43 X 1/2.16 = 43.43/2.16), and add the product of this multiplication (20.11) to 43.43, which gives 63.54

  Sorry if you've answerd this before, and thanks for taking the time to post your formula.

  For those of us raised in Europe fractions are some kind of ancient druid type black magic, so I've translated the above passage into decimal wording. (I hope)

  You must determine the fraction that the slope (6 inches) and the stated distance (13 feet) together represent: 6/13 = 1/2.16

        divide the distance 13 by the slope 6   =  2.16

  You then multiply 43.43 by this fraction (43.43 X 1/2.16 = 43.43/2.16),

        Divide the original offset (in this case) 43.43 by the slope fraction (2.16) 

          43.43 divide by 2.16 = 20.11

  and add the product of this multiplication (20.11) to 43.43, which gives 63.54

        add the resulting number to the original offset i.e. 20.11 + 43.43 = 63.54

  I hope this is an accurate translation from fractions to decimals (I'm pretty sure it is) and that it helps.

  First thank you for a. working this out and b. posting it. It has obviously taken a lot of time and effort.

  I've been trying this now for 2 days and either I'm doing something wrong or things have changed since this was posted.

  I use the distance method according to backswing posted in putting tips elsewhere on this site and work out the lateral adjustment by a combination of feel and moving the aim point a bit every few lines I observe, I almost always end up either in the hole or within 2 feet of it. Using this formula each putt takes between 10 and 15 minutes and I never end up within 10 feet unless I'm already close.

  However, it obviously works for many others, so again thank you for going to all that effort.

  Great Information!!

  Makes you think for a moment......

  1.) Does this consider individual monitor sizes? ie 17-22...I use a 46"monitor.

  2.) Does this consider individual monitor resolution settings? ie 1280 x 1024 vs 1024 x768 or 1600 x 1200?

  just saying

  G0LD:

  b) You take the stated distance between you and the hole: 13 feet, and adjust this number by factoring in the slope. In this example the slope is 6 inches downwards (shown by the color red on the grid, whereas black shows a flat surface and blue an upward one). You add this number of inches to the number of feet, which gives the number 19. 

  If the slope were upwards, you would subtract the number of inches from the number of feet, instead of adding it to the latter. 

  Thanks for sharing your formula, I'm going to give it a try.  I'm confused by the calculations of distance.  Why am I adding the elevation for downhill putts and subtracting it for uphill?  This makes no sense to me.

  Please explain.  Thanks.

  The reason you add for a downhill slope is due to the fact that downhill putts break more because you are putting them at a slower pace. The same goes for uphill. You subtract from uphill because you are putting it harder... which means less break.
