In addition to the above that was already shared, I continued to test and work with Danny's formula...I am still testing it and trying to fine tune it, but since we exchanged some PM's he mentioned I could share it here to save him from typing it again...if it helps further, so be it hopefully it doesn't confuse us more...
"I did your calculations for the entire length of the putt but since it straightens out the last half this obviously would be the wrong break or aim point...so, I estimated the break was only about 60% of the entire putt. I then took the original aimpoint and multiplied by 60%"
I do what you just described all the time. Except that I use exact multiples or halves... or halves of halves. Why? Because if it's anything other than a multiple of what you counted for dot speed, then the count must be wrong. At least in my experience. That's part of the recurring number patterns I mentioned above.
"I have also used aim points and relied a bit on some of Tekoma's tips. I know some people regard Tekoma as a little bizarre, but if you can see a good line one of his methods usually lines up with it. It gives me more confidence knowing I see something that aligns with something else."
I agree 100%.
"then did the calculations and used Jason's ruler "
I don't think I've seen Jason's ruler. But You don't need one to measure accurate inches of the grid. As a matter of fact, a ruler overlayed on the screen can't give consistent perspective because of camera angles and, more importantly, the hole is not always the same distance from the camera. I just unlock the putting grid and measure every inch of the grid just by know it is 24" wide. Whether it's closer to the bottom of the screen or backed further away from the camera. That said, that dude drains a whole lot of putts. So go with what ya know ;)
"The thing I will have to check is I have noticed that sometimes the break at the beginning of a putt influences a putt more than the break at the very end of a putt."
Yep. My take is that that initial break throws off the initial "angle" a little bit. So now the ball is already turned more down the slope than you originally hoped and it never has a chance. That will be where experience kicks in. Sometimes I'll make an effort to slightly misding into an initial break because of that. More on a downhiller than an uphiller though.
"thought PM would be better since this part of discussion was past...."
No problem. My general forum posts are still moderated, so they show up a day late. The thread reads pretty awkward because of that. I think I have to have 40 or so general forum posts before they show up live. Anyway, feel free to post any of this to the forum. Might help some other folks lurking. And save me from typing it over and over again, LOL. Just kidding, I don't mind at all.
