BPEL vs length in Cylinder

Anyone else have a discrepancy between BPEL vs length in cylinder. My cylinder length max is perhaps 3/4” less than my BPEL. Is this common? Am I measuring my dick wrong?

You may need to clarify. Is it that your out-of-pump measurement is larger than your in-pump measurement? Usually, you’ll find the reverse.

That’s correct. My in pump measurement (marked on the outside of the cylinder) is shorter than my BPEL outside of the cylinder.

Does your cylinder have a 1/2” thick flange that is not accounted for by the length markings on it?

I’m also like that 19cm BPEL [precum when fully erect] and only 18cm or max 18.5 inside the cylinder.

But girth wise way bigger inside the cylinder.

I was thinking of making a thread about it few days ago but I was too lazy.

Have you verified the measurement on the outside of the cylinder with a ruler? The “sticker” on the outside of the cylinder may not be accurate or the “sticker” and May not have been placed properly

No. I marked it myself. I’m guessing that It’s just harder to compress my fat pad with the area of the cylinder than with a ruler.

Do you have a very large fat pad? Perhaps you are sliding the ruler under your pubic bone which is easy to do if you hold the ruler flat along the top of the penis. Have you reviewed this?

Thanks for that link. I do have a fairly thick fatpad…. 1.25 to 1.5, even though I’m a lean guy. Next time I’ll use the ruler turned 90 degrees and see what I get.

I have decided to start a regular pumping-only routine. I’m still trying routines and I don’t know if I should start a thread for this. I keep everything annotated on personal sheets every day.

About the BPEL, I’ve noticed that in my case it is proportional both to pressure and time. The more pressure and the more time, the longer the BPEL max inside the cylinder. But I haven’t gone over 10Hg and neither over 10min.

The BPEL max inside the cylinder is longer than my BPEL. It’s not much though. I don’t know if I should measure this. The measurement would be something like “I reached a BPEL of x inside the tube at 6 Hg after 10min”.

I wonder how cylinder size affects this. I’m using a smaller cylinder and when I start pumping I’ve already packed a good portion of it.

Update:

I switched up to a 2.125 diameter cylinder, and I’m only about 5/16” short of my BPEL. So I’m guessing that sticking to the sides is preventing my dick from stretching to it’s full length in the tube.

Thanks.

I have found something similar as I get more pumped length in my 2.5” cylinder than I do with the 2.25” one, even with a well lubricated shaft. Logically I would expect to see more length when (partially) packing the smaller cylinder, but that doesn’t seem to happen with me.

Thanks for confirming. This goes against most of what I’ve read, so I’m glad to know I’m not the only one.
