No, not Steve Cook. It's someone who doesn't always use his real name, so I'll leave him nameless here. He was the guy who brought the mini-skirted young lady to a match he played, as mentioned in this article on sharks and scams:Jimmy M. said:Hmm. Was it Steve Cook? I'm just trying to think of someone who might have played one pocket at that speed.

As for Ted, who steps off angles with his hand in Mountain View, I suspect that if someone worked at it for a week with good tools, he could learn to estimate angles within two degrees without measuring by hand. I doubt that the hand method gets more than 2-degree accuracy, and that's not close enough.
