A. (lengthen) topspin -- when an object ball rolls into the cushion, it has topspin. Some of that forward spin can remain just after the bounce (that is, the ball is coming back, but it is still spinning forward a bit.) This leads to the object ball curving back toward the rail in a masse-like effect. The amount of topspin that remains will depend on the slickness of the rail cloth as well as perhaps the profile/height. Also the stickier the bed cloth, the sooner after the bounce this happens and the bigger the apparent effect. This effect would be really big on new rail cloth and old bed cloth. [Banks hit hard come off shorter primarily because this effect is missing--the hard-hit object ball slides into the rail instead of rolling into it]
D. (shorten) -- the crunched cushion wanting to spit balls straight out -- I don't know if this effect is real or not. My tendency is to think it is more myth than reality. I'd be interested to hear what Dave A or Bob J think.

The reason the red label Diamonds bank short is the sub-rail angle, the side of the cushion that attaches to the table is different. The nose is rolled over to make the nose height the same but the angle where the cushion mounts to the table is different.
So the easy answer could be explained as easy as rail thickness but I think you could have equal thickness rails and still fudge the mounting side of the cushion and have correct nose height.
I will say the easy answer is the angle the cushion mounts to the table affects bank angle.
Is this correct Glen????
Every table I play on banks short...or long...
...I'm not very good.
I suspect another factor with topspin is that "softer" cushions degrade topspin more effectively due to the increased friction from the larger contact patch as well as the increased contact time and this in turn would obviously have some affect on the rebound angle for balls that were rolling when they struck the cushion.
