That is curious. Me and most of my group picked up the basics from a 10 minute phone call to Hal. Makes one wonder how a guy as smart as you claim to be doesn't have the slightest clue how to use it. I mean just follow the objective instructions. What could be so hard about that. Then it takes a little time to work with. After all it is a complete playing system and not something you fiddle around with in practice but dont use in a match situation, like some other system on here.
PS i love how you overstate things
The objective basics are simple, you're right, but that only includes the two-line perception. The other steps require experienced judgement and are only simple to those that have such experience.
The pivot is the only thing that is really tough to understand it pick up. I've watched Spider's CTE Pivoting video and that makes it even more cloudy, mainly because he's using 1/2 ball pivots instead of 1/2 tip, but I realize that's the original CTE and 90/90 style pivots. Spider shows how a fixed 10" bridge won't work. Then he states that the sweet spot for pivoting is between a 10 to 12 inch bridge. He then demonstrates a strict pivot from the bridge hand followed by a squishy bridge hand pivot where he says it feels like he's really pivoting the cue at about the joint area. But he's not. In both examples the cue pivots exactly at his bridge hand -- coach's eye app shows it with no doubts. That's about as clear and accurate as mud. But he is entertaining, seems like a funny guy, witty.
