Ok, that's cool.
Actionable info:
1. There's a single target point for all equidistant putts to a hole cut on a plane.
2. The target point is directly above the hole.
3. The farther the putt, the higher the target.
4. The target is the same for all putts on greens with a common slope/Stimp product.
4 is quite interesting from a GCA perspective, as it effectively proves that some putting characteristics are mathematically equivalent along a strict inverse relationship between green speed and slope.
