Bill,
Rugge makes that comment at the end. Just play what you like. I have been told that feel is really non-existant. Its more a matter of the sound of the ball, since you really have no connection between the club/ball interface. That could be a result of cover material, thickness, etc.
I recall touring the USGA testing facility when Frank Thomas was running it. He got a lot of questions, most of which he sidestepped nicely. However, he did comment that Bridgestone balls (this is ten years ago and may have changed) were the closest to the 255 ft/sec limit overall. Because of tighter construction tolerances, they were able to be at 254.5 rather than the 253.75 of other mfgs and still pass the 99/100 balls required to be legally within the limit.
So, I guess at the 2.5 Yard per MPH multiplier listed above, you probably get another 1.875 Yards, which I am sure you noticed.....
