Jelqing under BPEL- still gain length?

I’m coming back from a jelqing related injury and I had a question about lower erection jelqing and length gains. For example, I’ve jelqed at lower erection levels in the past and had my doubts if it was even effective because my penis remained much smaller than my maximum erection size. Say my BPEL is 7” but because I’m jelqing at 20-30% then my penis never gets over 4”. How would I be able to gain length if I’m not jelqing past or near my erect size? I know I could just ad a stretch at the end of the jelq, or stretch separately, but I’d really like to follow a jelq only routine. What do you guys think about this?

Its not about stretching past el with jelqing. Its about getting expansion due to more blood flow. But scientifically I also wonder how it grows if its not getting pushed past its maximum size. I would think clamping would be more effective for expansion. Anyway, I don’t really know, but I do know that jelqing works.

I can’t say anything intelligent about the science of getting length gains from jelqing, but what I can say is that I was able to achieve a substantial increase in BPEL by following a manual stretching and wet jelqing routine. Also, when I tried a manual stretching only routine over a 7 month period, even though my rate of BPFSL gain increased, my BPEL gains lagged behind BPFSL. BPEL and BPFSL increased pretty much at the same rate when I was following a manual stretching and wet jelqing routine.
