Packed the pump: What's next for length?

Slowly built up from 15 minutes now I could pack the whole pump girth wise in 30 minutes with 5 mmHg pressure with constant heat. Doing this 2 to 3 sets per day. I’m mainly aiming for length, with girth as a secondary goal, anyway. Wonder what to do next once you packed the tube, as I’m worried going further might cause blisters on my glans as the entire vacuum is being subjected on my glans. Should I:

1) Drop down the pressure once I packed the whole tube (5 mmHg to 3mmHg and keep going), aiming for increments of 5 minutes per week?
2) Increase the pressure to 6 mmHg at the start and end it once fully packed the tube?
3) Keep it at 30 minutes to fully pack and at 5 mmHg but increase the number of sets?

I’m ruling out changing to a bigger tube as I tend to gain girth naturally and this always seems to impede my length gain.

I faced the same dilemma and first chose to try a silicone sleeve. I pumped just until the cylinder was packed. I fit a silicone sleeve over my erection and put it back in. I was blown away to see the tip of my penis slide easily past my prior max measurement.

I continued that until I decided to buy a bigger cylinder. I still use the smaller one to “warm up” for the larger model - where the sleeve is still helpful in eliminating edema.

Good luck
