The rub or difficulty is that is that HIF and plastic deformity theories are different pathways and thus you’d approach them different. HIF can work with IPR theory but IPR theory also doesn’t jive with plastic deformity theory.
Obviously normal clamping programs over the course of a year would see a cumulative time factor well beyond the mags-phallous range of 16-30 or so hours in that same year.
I used to be all about plastic deformity, it made sense to me based on those ear rings that cause holes in your lives to spread wider and wider, or African women stretching their necks with rings and with lip plates. Also people going after foreskin replacement.
Not to mention clamping became the go to girth exercise under that theory.
BUT
Based on my own experience I think HIF works by a different mechanism and instead of structural integrity being warped, the low oxygen state seems to turn on a “switch.” To grow.
When you consider that people consistently report that it’s the base, the part under the clamp, which is the most constructed not the most expanded—that grows the thickets I think you could see that sort of effect in play.
I suspect just like with ligs, you can get some play in the tunica etc. Some people responding more than others. But sudden hypoxic shocks followed by long intervals without significant stimulus is what grew these mega cocks.
I feel pretty good about that line of thinking at this point, but I’m by no means a zealot who thinks he knows more than everyone else. My only real point is if you choose the plastic deformity route then more is more and better and in my case I quickly reached a point of stall under that school.
