Launch monitors vs short game ¶

Hi Tyler!
I don’t know if it’s made your radar, but there’s kind of a low-key war between two short game schools on the internet. One advocates a steep angle of attack and the other advocates a shallow approach, and both boast active successful tour players who use their respective systems. The steep guy consistently points to Trackman data that shows an AoA of 10-15 degrees, and the shallow guy points to an attack of 2-4 degrees but uses GC Quad, and both seem to have spin rates north of 7500 rpm for 10 yard pitches.
I don’t have a launch monitor, but I did a little video comparison using right triangles in a series of stills to approximate AoA at different distances from the ball and found that on a successful short pitch for me, about 18 inches from the ball my clubhead is dropping about 12 degrees but closer to the ball my attack is much more shallow; less than five degrees. It made me wonder, what part of the actual arc do Trackman and GC Quad measure? Is it possible that they measure the arc at different points and both these guys are actually advocating roughly the same motion? Watching their players in tournaments, ther doesn’t seem to be any kind of drastic differences in performance from either system.
Then it struck me that this is precisely the kind of tidbit that you might know.
I’d appreciate any light you can shed on the subject!
Thank you,
Zach
