Thanx Doc
I think most modern rails are too low.In the Theory of the Ball (written
in the late 1800's)it says the rail height should be about 70% of the
ball's height.At a lower height the ball goes air-born.At a greater height
the ball is pinched and bounces air-born.
An old Brunswick owned by Frank Taberski had higher rails and played
great.I feel the lower rails are to accomodate the average player who
can't shoot a frozen cue ball without miscueing.
As usual, watching you videos is time well spent.Good answers. I can think of many more along these lines, but they are also silly.
Another possibility is if the cushion could somehow convert the rotation of the ball into stored energy that could somehow be returned to the ball as translational energy, but I can't imagine any way this could be possible with regulation pool equipment.
Again, I think this video explains and demonstrates the physics quite well:
The CB looses quite a bit of speed off a rail, even with slick conditions.
