frypup;
To clarify, I gained 1 inch with pumping alone - no other PE exercise. Then incorporated jelking and other exercises between pumping sets and gained just short of 1.5 inches more. I’ve lost none of my gains. The longest I’ve been away from pumping or PE in 2 years, though, was only about 3 weeks at one stretch. Pure pumpers (no other form of PE) tell me that they have lost gains when they quit pumping for many months, though they did not revert completely to their original size.
“Also, do you recommend always staying at about 5 HG when pumping or increasing it gradually over a period of weeks or months until you reach a max of maybe 10 HG?”
This is a totally subjective, individual decision. I just passed the two year mark of pumping, with a heck of lot of other PE thrown in. You would think that I am conditioned enough by now to handle very high pressures but that is not the case. I can’t even get to 10 HG for more than a few seconds without pain and bruising. If you can get there without any damage or pain, gradually go for it.
“Finally, do you vary the amount of pressure within a single session?”
I usually pump while watching CNN or some other TV diversion. I don’t pay much attention to my gauge anymore because I can always tell where I am by the feeling. During that time I am anywhere from 3 HG to 8 HG, up and down in that range. I have to keep adding pressure from time to time because I’ve never been able to keep a perfect seal. I do this on “automatic pilot” at this point.
Hope this answers your questions.
