"This is the problem I have with the formula. It often produces breaks that seem wrong based on instinct."
In my humble opinion, Saltiresfan, if your aim is wildly wrong, even if you rigorously follow the math, then it is your timing of the dots that is at fault. I should had that my formula is particularly well suited to tournament greens, and require some subtle adjustments on slower greens, especially on downward slopes.
I invite you and everyone else on this outdated thread to do the follow-up on the updated one at this address: http://www.wgt.com/forums/t/99536.aspx. Please read my update, in the hope that it will shed some light on some obscure points.
Thank you.
