Different people obtain their cap in different ways, I guess.
Super low rounds aren't my thing, but I rarely blow out either. 2 rounds in the 20's this year, a 26 out of nowhere in the first round of the CoC, and a 28 where I only needed to regulation 2-putt the last for 30, and 4-jacked it.
25 rounds under 30 point in 5 years (164 rounds).
So I know when I step on the first tee I have an 84.75% chance of having 30 or better points.
