The pace of the putt is always going to affect the line, so
for me pace and attempting to play 1 to 1.5 feet past the hole is key (never up
never in) once you have the pace then the line of the putt tends to sink in with
trial and error.
Sorry I can’t be more scientific, but putting in VR is like
RL “touch and feel” and most of all practice.
For what it’s worth I tend to be a ding putter on any putt
more than 6 feet less than that I miss to compensate for the break and hit
hard.
