My second week of pumping started with 10-minutes sessions four days in a row. During these I pumped up the pressure to 5 inHg and then after a little while released the pressure. Rather amuzing to see the penis so fast getting smaller and softer.
After having shaked my penis a little in the pressureless tube I have once again pumped it up to 5 inHg. This cycling routine feels very good and I enoys the feeling of growth and slight tension as I pump up the pressure.

At 5 inHg I have used the tube's scale and noted that my penis is 19.5 cm long.

A couple of times I have pumped up to 6 inHg for the last cycle, here my penis have been 19.7 cm long.

During the week's last session on thursday I tried a different variant where I slowly pumped up the pressure to 5 inHg and then kept it between 4 and 5 inHg during the rest of the 10 minute session. Also this time I measured my penis length using the tube's scale and it was 19.5 cm.
When I ended this pumping session I took a measuring tape and measured around the middle of the shaft and the semi-erect penis was 13 cm in circumference.

I did not measure the length outside the tube.

The week ended with three busy days without any pumping.

Some cylinder concern:
When I ordered my first pump it was on the web site stated that the depth is 22 cm. That was a good thing for me since most pumps in Swedish shops are 20 cm deep. But when I got it I discovered that this was not accurate, the depth is about 20.5 cm.
My BPEL to start with is 18.5 cm, and now I have seen that at a pressure of 6 inHg I reach 19.7 cm. So naturally I am becoming concerned about what to do if my length increases another cm. I have a slight hope that if the penis can't grow in length any more in the tube, it will grow in girth instead. That would be really nice I think, but I am very uncertain about this.
