A question regarding length differences in and out of the tube

So at the moment I have a 6.0 inches BPEL, and that’s pressing the fat pad and getting to the bone it feels for that measurement. I’ll notice that when I do my vacuum pump at around 4-5 inHg pressure, I’ll have the tube packed at the base and my erect length will get out to 6.75 inches (I currently use a 1.75” diameter tube and have 0.25” markings along it to make measurements). Now is this just the hidden part of my erect penis being pulled out from my body to fill the tube via vacuum? I would assume so since a 0.75 inch difference coming from the immediate expanding of tissue would be insane! So my question is, do I track gains by seeing how I grow from my initial erect length in the tube? If that extra 0.75 inches is from my penis extending from inside my body, does that part ever stay out permanently (will a ligament be stretched over time to allow such thing)? Or do the gains mostly come from growing lengthwise and not necessarily pulling out what exists?

Also, pumping while also doing extending via an ADS, do I want to do my pump sessions before the ADS, after the ADS, or does it not matter?

pump after the extender, for pumping before will give you grip problems.

To keep track, you should measure as usual, for what you see inside the tube is just the strain.

That said, I must also say that in 10 years of pump use I don’t have a single milimeter gain in length, and little to no girth gain, all in the base, mid shaft and upper shaft have no changes. What am I implying? well, I’m certainly not saying it wont work for you, but I’m saying you should keep track for if that happens to you too and see no gains in less than 10 years, maybe should opt for another method. Extending did work for me, and I ended leaving pumping for pre—sex days, so it’s fatter for the encounter but it just lasts one or two days at most.

All my gains are from pumping.

What is your BPFSL? Is it close to your max in tube pumped length?

My BPFSL is also 6.0 inches, and that’s pressing the ruler as deep as I can into the bone. Just today after doing my extender (Penismaster Pro) for about 4 hours ,I was able to get to 7.0 inches in the tube.

I have always been shorter in the tube, seems to expand mostly girth wise. I have gotten some pretty good girth gains mainly from using my bathmate.
