Usually I think it's no big deal, in the past dennis had tried this but basically failed... people were talking like every rack was the exact same but they weren't at all.
Obviously though he figured it out, at least for the three racks at 15:28, 18:35 and 22:00. It's not as horrifying as Corey's where he makes 2 balls and then combos in the 9, over and over. But it's to the point where it's getting abusive.
There's a specific WPA rule forbidding it, and refs and other players either don't know it, or pretend like the rule doesn't exist.

Also, for years, a completely logical and realistic solution has been proposed to racking problems. And for years it's been shot down as impractical, too problematic, too unfair or expensive or whatever. That solution is a neutral racker.
It's not rocket science. A 7 year old can get a tight rack with a magic rack, and a 12 year old can be trained to do it with a standard triangle. There's often a ref or TD standing right there during the finals. Nobody's gonna ask for $30 an hour to do this. Probably you can get free volunteers.
They say this would open up a can of worms... how would you describe the current situation where players leave gaps intentionally, or pattern rack, or waste 20 minutes trying to freeze them?
