Thanks, Dave.

Here's a summary of what this video shows:

In other words, dirty conditions do not produce faster rebounds; in fact the opposite is true.

Slick conditions produce rebounds that are:
- 1/3 faster with follow
- the same with stun
- almost 2/3 faster with draw

a polished ball coming off a rail maintains more top spin which then translates to backspin off the rail, momentarily slowing the ball until the backspin is lost to friction. if you don't believe me you can see it for yourself by waxing a ball and hitting it into the cushion with follow, head on but you don't even need follow to see the effect. some "trick shots" are based on this phenomenon.
