Ok maybe for you. But for someone who aims whilst standing... How ever they choose to aim... It is very difficult to then accurately judge to hit a certain part of the pocket once down on the shot by adjusting. Or when you have a ball and a half gap to one side of the pocket... They are much better adjusted for whilst standing. To do this well, a player has to find a line of aim that sends the object ball through the gap. A centre pocket line of aim won't help, and will likely distract a player.
You have 6 decades of table experience, so I'm sure it is second nature to you to adjust for parts of the pocket being blocked. But for someone who is new to CTE it would be tough, and would take time for them to learn how to do it... Or fill their memory bank with successful shots in other words. Any system... Or no system... If they practise it and learn to adjust then isn't it just like anything else in pool...you don't need a system, just experience which kind of makes using systems a waste of time IMO.
What I would like to see from you Stan is you making videos on combinations and hitting the 3 sections of the pockets for all perceptions. I feel it may help new comers to CTE learn faster and force them to use it every shot. You know how it is... League player, a 1-9 combo for the win... CTE won't help unless it's dead straight so they go back to guessing and miss making them doubt if CTE is usable in tough situations. I admire the curtain videos... But I can't ever remember having to shoot through a curtain for the win.
This isn't me having a pop at you by any means, im just expressing my opinion and letting you know what I feel is missing from CTE.
Cheers.
