This is an extension of the original work by H.A. Templeton (Vector Putting). It turns out there is a very beautiful underlying geometry to putt trajectories which amounts to the mapping of a circle onto a diamond. While I know the math can be oppressive, the gist of the paper is summarized in Figs. 12-23, which are images of putt trajectories. The point to the paper is that when lining up a putt it is useful to look at putts a couple of steps to the left and a couple of steps to the right.

The ultimate "Cheater" Line.

This is a good example of why greens shouldn't be planar.
Cool video

Good to see that the Yale Dept. of Applied Physics is spending their grant money well. This will be great for pace of play too.

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.
