agreed. but we are not talking about preferences or opinions. He said bob jewett is wrong. I (personallY) trust bob jewett.
As I read Bob Jewett's first post in this thread, it sounded like a rationalization to me, like: "Yeah, Sardo's make divots, but divots don't really matter."
Well, I wonder if Bob would say that to somebody who started hammering balls into HIS table!
Focusing on details is a common way to avoid the point in someone else's argument. The simple idea is that it's preferable to avoid doing things that disrupt the surface of tables. IMO the "magic rack" is a brilliant solution to that issue.
I also understand mechanical physics and my own knowledge tells me that the static friction of the balls is what holds them together and the impact of the divots is minimal, and only enough to make sure that static friction can do its job. I find it hard to believe that a microns deep compression of wool cloth can affect the inertial moment of a billiard ball. I really do.
Bob Jewett also said in another post: "Yes, as I pointed out in my original post, settling while stopping can happen. It also occurs in the rack area on worn cloth or on the spot on fairly new cloth."
So, he SAYS that such a divot CAN cause balls to freeze together that wouldn't otherwise. What are your qualifications for implying he's wrong?
How can you argue with someone who says it's better NOT to have that potential on a table vs having it--even if it's extremely rare?
