No way it's a bulging spot.
If it was bulging enough to cause that radical of a curve, then it would bulge enough to cause the CB to hop, skip, skids or do other strange things on other shots. No way after 400+ balls on this run alone that the axis of the shot and the bulge did not come into play earlier.
I'm certain than upon inspection with a micrometer, the ball will not be perfect as NO ball is. The question is, how much out of round or how much of a small area bulge is necessary to generate that kind of curvature?
I don't doubt that even slight variances can cause stresses when spinning when you look at various mechanical objects in our world where balance is critical. How much is the question. It's really hard to imagine that with all that play, a player like JS would not notice a bulge on the CB. This is something he might be able to see. And certainly feel.
Occam says that the slate is F-ed up in that area. I've seen bad rolls and it's almost always slate.
I hope Bob can get a hold of the CB. If this theory is true, then this effect should be repeatable.
I predict the ball measured will show inconsistency.
I predict it is not enough to explain the effects.
I predict the effect will not be replicated.
If I am wrong on the above, this will create a new series of questions regarding Saluc Aramith and their quality control. The design or manufacturing process for this CB or any ball for that matter. For the kind of money they are charging for these premium ball sets - this should NOT happen. Wear is one thing, this would be blatant defect.
It won't be good to be known as the junk CB brand that ruined what was highly likely chance to break the high run record. He was 92 balls away. The way he plays, the record was probably toast if not for that freak CB behavior.
I would agree, not as a science guy, but just a pool player.
It looked to me that the slate might have had a corner cracked sometime in its life and been bondoed back together but just not perfectly and the CB hit that seam. Total speculation but that makes way more sense to me that all the other theories combined.
