4hg doesn't give me good expansion anymore?

Usually I pump at 4hg and I get a good expansion, I pack the tube about 1/3 of my dick and my length in the tube is just above my BPEL (+0.1-0.2”),
I always use IR-lamp when I pump.

Yesterday I hadn’t been pumping for about 30 hours and I noticed that I didn’t get a good expansion at 4hg. I could swing my dick inside the tube and it didn’t feel as hard. I had to pump to 5hg to get the good expansion I did before.

This is not the first time I pump in the evening, and the day before in the morning (30h between), so my question is why doesn’t 4hg give my any expansion anymore?

Edit: Earlier the pressure could drop to 3hg and I still would get a good expansion.

Sounds like it’s time to add just a bit. Quite normal and I tend to think new gains are headed your way.

I agree, it is time to start increasing pressure, but you still want to always begin your routine by starting at a lower pressure and increasing every 5 to 10 minutes. So if you are used to starting at 4”hg, start there and increase to 5”hg after 5 to 10 minutes. You may even want to explore increasing to 6”hg after another 10 minutes, but go no higher until you get fully conditioned at that level. You could easily stay at that level for 30 days.

You mentioned not pumping for 30 hours as though that was a long interval, but I hope you are taking regular rest days. At my current level of pumping, I pump every other day for best results.
