Measuring while in the tube

I posted about this in the newbie section and drew a big flat blank in responses so here goes again.

I scratched a line in the plastic of the cylinder that I use for length work at the end of my erection on a comfortable psi (7.4”) and another where the pressure is the maximum I can stand without pain (7.6”)

When I measured my length out side of the tube, the tape showed about 6.8”. Is 6.8” my BPEL or is it what it reads in the tube?

I would stick to what you measure outside the tube, it’s a real measurement that way.

BPEL is a full regular erection measured with a ruler pressed to the pubic bone. The measurements under vacuum devices are not BPEL and they can be quite a bit longer than normal erection lengths.

My maximum pumped length inside the tube is an inch longer than my normal BP measurement.

Thanks guys. Does that mean I have the potential to reach 7.6” in length? I’d be delighted with that! However I’d trade any future length gains for another half inch in girth! My dick is so ridiculously thin! I know I’ll never have the kind of cock that can wear a wrist watch, but it would be nice not to have to buy small size condoms.

Don’t know about length without additional methods but pumping is definitely good for girth.
