Once I went to a 1.75” cylinder I started pumping longer, to 7”, and eventually packing after about an hour.
I have a 2” and the 2.25” tubes, but rarely use them. I stick with the 1.75” tube. I now pack it in a couple minutes and can reach 8” in the tube.
My current stats are around 6.25” NBP and 5.5” girth.
My general observation is that you should be able to stretch 1 - 1.5 ” beyond your NBP length at max extension in the tube. Thats at a maximum comfortable vacuum.
Packing the tube and reaching 8 inches from 6.25NBP in 2 MINUTES!?! What pressure are you using? Correct me if I’m wrong, but I suppose this is because your girth when pumped is relatively the same size of the cylinder, so once packed the vacuum force pulls the penis up? I am 5.125 ” girth using a 1.75 tube and looking for the exact process to happen, ie. length expansion and stretch beyond typical max of 7.125 BPEL. However it takes me at least 45 mins to an hour to begin to pack the tube so little if any length expansion occurs during my workouts. Patience and consistent workouts over time is probably my best approach.
