Agree that it depends a lot on the kind of player you are.
I have been as low as a 1 in the past, now I'm around a 4. After my son was born I played barely at all in the first year of his life. One of my first rounds after I started playing again was with some folks at the very long, very penal Quintero GC, from the tips. That day was a big struggle, but I still broke 90. On my handful of worst days I might threaten the 90s, but I can't recall the last time I actually shot such a score.
For me, I drive the ball very well, generally. Hit it a reasonable distance. Not real long, but long enough that length doesn't intimidate me much. My primary struggle is with short irons and putting. So my variance in scores tends to be very low because the difference between a really good day and a bad one is, maybe, a bad drive or two, and how I putt. I'm sure there are courses out there where I couldn't get down in 4 putts, but I haven't found one yet, and it's have to be that kind of extreme before my scores got so bad that I was seriously threatening 100. Even my worst days driving the ball, even on tight, penal desert courses, I can get it in play more often than not.
On the other hand I have a buddy who can play well enough to break 80, but can also easily be over 100, or anywhere in between. He can be good but there's really no part of his game that is consistent at all. I think if you can get consistent with any mjor part of the game, you can go a long way toward taking those big numbers away.
The US Open set up examples are pretty extreme, and pointing out that even good players can struggle to break 100 in those conditions doesn't seem to prove much except how extreme those conditions are.
