It's a fact. The results of computer modeling that's dead on accurate.
This particular putt is never within 80 degrees of the fall line.
I don't know what you're missing. These numbers demonstrate fairly clearly that the last part of a putt isn't more important than other parts of the putt. Perhaps you are not considering that when a putt has already broken 26 inches the angle it is taking has changed and perceived break is larger than actual break.
It would take far too long for me to explain all of the physics and math in this. Trust it, or don't. People are too wishy-washy about putting and treat it too much as an art form when green reading can really be resolved by learning and applying a few very simple skills.
I am not saying you are wrong about this putt but I don't see many facts about this particular putt other than it is 20 feet, breaks 32" with 6" of break coming in the last 5'. I fail to see how you calculated 32" of total break or 6" coming in the last 5'. Is there a place where I can get more information about this putt? i.e. what is the slope of the green and at what angle is the ball and hole relative to the fall line..
By the way, when you say "the angle it is taking has changed" is what I meant when I said "...the first part of the putt has broken towards the fall line and the last part is more down the fall line than the first part."
I'll also add, just because a particular putt breaks less at the end doesn't mean that watching the last part of a putt fails to convey valuable information. If a putt stays perfectly straight the last 5', that would help me to determine where the fail line is or show that the green is very flat around the hole (assuming that the player striking the putt did not put a lot of side spin on his ball that was still present the last 5 feet).
Do you know if anyplace in Summit County, CO that offers Aimpoint?
