Manich that is very odd. If that is true shouldn’t your full erection after pumping be at least as long as your semi erect pumped measurement?
I just got my cylinder today from Vacutech, thick walled 9x2. I admit its a little spacious but that is what I got the pump for, the girth work! I did a dry run at 5-10 hg , anymore felt uncomfortable. I can see that the skin will likely take up fluid and give a false girth gain so I will try condom pumping later tonight. I love how my glans inflates, much better than what I could ever achieve with squeezing I think.
