I use to work with Gold a bit on his method. I went a different route in the long run that works for me... BUT Gold gets the credit for setting the foundation for my success in my method. U said above that you didn't understand why his numbers were different between his calculation and what you see on screen...
I haven't even seen the jpeg but I can probably answer your question...
The SAD fact is that WGT hardly ever provides the CORRECT info when approaching a putt. It can say 13 ft in the upper right hand corner.. That doesn't mean it is 13 ft... It could be anywhere from 13ft to 13.9ft... If you are in putt view... click and hold that blue arrow and drag it before the hole and after... You can get a good idea of exactly what the distance to the hole is.
When i use to talk with Gold he was all about leaving putts that miss 2 ft. or so past the hole.. (Your putt NEVER has a chance to go in if it is SHORT approach.)
The downhill break explanation is just a guess but...
If he is on tourney or champ greens 3 inches downhill is more like 5 or 6... especially if it appears to keep on heading downhill after the hole.. Again WGT doesn't provide all the info. it can be anywhere from 3 to 3.9 inches downhill.. Heck could even be less because wgt takes into account slope before the ball...
With a system like Golds or My Nei Way of putting... The system will never be perfect because WGT does not provide all the information needed to be 100% correct on a putt...
Maybe one day wgt will add decimal points for putts past 10 ft. Just is silly that they don't do that...
HOPE ALL THAT RAMBLING HELPED.. I haven't visited this thread in a long time
