Hi Darkengine
I think there is a common ground to expansion through jelqing or pumping/clamping - and there are differences.
Common is to all 3 exercises to create growth through expansion creating micro-fissures in the tunica.
Differences are the way the expansion gets created. Pumping creates stress from outside and the expansion is immediately visible. The stress is static (as long as you stay at same vacuum level) and acts, depending on tube diameter, on the entire penis. Clamping is the opposite way, the stress is created by over-pressure inside the tunica. Clamping is a static way too, as the pressure is created and held by the clamps. For this reason, the expansion is, as in pumping, immediately visible or at least measurable.
Now jelqing is different as it is a dynamic technique. Basically you create a local over-pressure that you move manually like a wave through CC and (a bit less) CS. Therefore, the expansion is only local at the peak of the pressure wave, the tunica stretches and then goes back to it’s former state plus expansion. Because the pressure wave has created micro-fissures in the tunica, it is expanded a little bit and it will grow by creating new cells to fill the fissures. But you do not see the expansion of the girth and length by naked eye - we’re talking micrometers or even smaller for each jelq movement.
That is why expansion with pumping and clamping is immediately noticeable (but not permanent) while with jelqing it is nearly not noticeable as it goes at the same speed your biology allows growth.
I am quite convinced that it is not possible to say that one way of growing (immediately visible vs nearly invisible) is better or faster as all three ways depend on the same basic principle: triggering cell division for repair of micro-fissures. Therefore, it is only your individual constitution deciding which stimulus technique gives you the best and sustainable results.
Oh, and another remark: jelqing works even at lower levels of erection (40-60%) and the risk of injuries from vessel pops is smaller.
I hope this answers your question
