I can make shots with manual pivoting, the ones that just happen to work, the exact same shots Stan shoots under the curtains, plus straight ins using a 15 outside.
That's the allure to newbies. There have been one or two new players in this forum over the last year who try it and say, "Hey, this seems to work"! Then they tell you that their success rate is like 50%.
They don't have the experience to realize that some shots naturally go with Stan's system but some fudging away from the defined system is the only way all the other shots work. The problem is that they blame themselves when those shots don't go, which is counter productive to their progress, IMO.
