Thanks Scott for The Loop interview, it was very enlightening to hear your side of the story and the voice behind the words.
You mentioned that Will is 100% from 3 feet, but about 89% from 4 feet, compared to 92% tour average. But since 89% is so high, and 4 footers are infrequent, that it isn't a big deal in the big picture. (I am paraphrasing, so if I got that wrong my apologies)
I agree that looking at a single distance is probably not illuminating, so I analyzed putts made from 4-8 foot range for the top 30 in total strokes gained. My idea is comparing Will to the top players makes more sense than comparing him to guys happy to make cuts.
The table below shows strokes gained (or lost) for 4-8 foot putts per 72 holes for the top 30, in order from best to worst.
Notwithstanding Will's exceptional rate 3 feet and in, he loses a little over half a shot per 72 hole event to the top 30 from the 4-8 foot range. I imagine a lot of this is run good/bad. Rahm is probably a fair example of that.
I'm sure you've already seen something like this, but I thought I'd pass it along.
