What is the % tilt that's acceptable today? The front half of Pasatiempo #8 is 6%. No pins there. With greens stumping at 10, is 1% slope the maximum in pinning areas?
It would be great to see members accept 8-9 stimps. There would be so many more opportunities to put more tilt in the greens, and much more fun golf.
At 10' 2.5% is about the max
No, 2.5% is not the maximum slope that can be used for a hole location at 10' on the Stimpmeter, unless your criteria is that you should be able to easily roll the ball dead from above the hole. If 2.5% were the max, there would be greens on many classic championship courses where they didn't have enough hole locations for an event.
Garden City Golf Club, where I consult, has several tilted greens where pretty much the entire putting surface is between 3 and 5 percent. As Matthew's post shows -- and it exaggerates the problem, because we measure slope in % and not degrees -- greens above 3.5% [2 degrees] become very fast as an effective speed when putting downhill, and encourage you to leave your ball below the hole.
The USGA and the Tour WILL keep their hole locations to no more than 2.5% [actually the Tour goes down to 2.25%] if they have several spots on a green that qualify, but they don't always have that option. I have trouble believing that all the hole locations at Oakmont, say, were under 2.5% for any of the events held there. And remember, most weeks, the greens for televised tournaments are at speeds well in excess of 10' on the Stimpmeter, too.
I'm just tired of seeing the 2.5% figure bandied about like it's a black and white law. It's a milquetoast rule of thumb, designed to avoid any controversy. Clubs that are encouraged to change their greens for this reason are being fed a pack of lies.
