Can anyone out there explain the difference between say, 12 and 14? Is the difference one of degree, or moreso? For instance, is the difference between 12 and 13 the same as the difference between 13 and 14, or does the quickness go up exponentially as one exceeds a stimp of, say, 10.
My own experiece -- at a GCA outing two summers ago (in what is probably typical US Open conditions -- hot summer weather in the mid-80s) at Flossmoor (Tweedie, turn of the century, south suburbs of Chicago), we putted on greens that were, according to Supt. Bob Lively, stimping at 12.8 Lively is regarded as one of the best and most dedicated supers out there, i.e., I don't think he was pulling our legs about the green stimps. And the Flossmoor membership, from all reports, likes its greens quick.
Now, I may be the worst golfer who regularly posts here on GCA, and I didn't think the Flossmoor greens were crazy fast. Quick, yes, and you had to be really careful in some spots. But nothing goofy (along the lines of the video I posted on Oakmont on this thread). Flossmoor's greens are admittedly not severly sloped, but they have distinct cants, and being above the hole and trying to two-putt on them is a real challenge. But not a goofy one. I thought -- at 12.8 -- they were very fast, but very fair.
