Somewhere back there I managed to grasp the theory and design principles associated with the AI. Did you ever have a quiet personal conversation with Ackley on the subject of his various "improvements"? There is more than one way to mess up a finely made rifle.
I've never talked to Mr.Ackley but I've read both of his books. Have you done either? I also have been reloading for over 30 years and shoot through a chronograph when I develop all of my loads. I'll say this about your statement that "improved yields no results one way or another". You are wrong. Straightening the case walls and moving the shoulder angles from 28 degrees to 40 degrees allows the case to hold more powder. It's as simple as that. I can't believe I have to say this but... More powder means more velocity. I suggest that you stick with 22's and the old Ought Six.
