A superintendent friend of mine at a top 50 club gave a presentation to ASGCA and members while we played there. After announcing his greens ran at 11 everyday in the presentation, he told me later that they keep them at 10, but say 11 for the members benefit.
I mean, really, how many members watch the super use the stimp? So, its a little exageration that gives the members bragging rights, fast greens, and some reaonsable putts.
Like PGA Tour driving distances, I tend to agree with Jordan, based on that comment, that there is pressure to exagerate. That said, when I have played MV, which has been a while, they were clearly among the fastest greens I had played.
