Look, here is all that I need to know.
Amongst those who are currently playing, I'd rank myself in the #8 to #14 range. I consider Bolly, Lee, pricehcs, Angeltotti, and a few others that I'm not familiar with to be better than myself. Maybe Imcoola, craiger85, et al.
I'd peg my ability to shoot a low-50s CTTH at about 1/250, even if I took the exact same shot over and over again, and even if the wind was exactly the same every time (which it isn't) or if I got wind effect formulas directly from a WGT dev (which would be cheating.)
It is harder to shoot a 75 CTTH and a 30 CTTH than it is to shoot two 52.5 CTTH's. Proof: It is not all that rare for me to get two approach shots within 3 ft in a 9-hole round (10-30%, depending on what 9 holes it is [KIA #11, STA #9, etc. being 50-70% chances]), but it is exceptionally rare for me to sink an approach shot and get another within 6 ft in a 9-hole round (~0.05%)
The easiest way (by many, many orders of magnitude) for me to attain a 50-55 CTTH average over 20 CTTH rounds, then, is to shoot 50-55 over and over again, rather than some 65-75s and some 25-35s.
The chances that I can pull that off are (1/250)^20, or 1 in 9.0949...e+47, or 1 / 909,494,701,772,928,237,915,039,062,500,000,000,000,000,000,000.
This minuscule chance is about on-par with getting 15 hole-in-ones in a row on a par 3. It is impossible.
