Hi Conrad, Now that I've read the entire tome, I can answer more directly!
Yes, The feedback to PC is a very important and potentially adjustable feature. Back in the days of the Raging Bull, many people were increasing the feedback to force their AIM accounts to get back to fully invested. AIM did "buy on dips" but not as heavily as they wanted.
When the Bull died and the Bear took his place, suddenly PC additions of 100% or some other factor turned out to be way too heavy for the conditions. Sort of like a full set of sails plus a spinnaker during a gail!
Like many things, it's hard to find "one size that fits all" in a comfortable fashion. I agree that Mr. Lichello gives all of us as franchise AIMers considerable freedom to fiddle as much as we want. The fiddling makes it less "automatic" but seems to satisfy some need by many in the AIM community.

Best regards, Tom
