Progress table for 6 inHg

The previous week I listed in-cylinder length at the end of pumping session at 5 inHg that lasted 10-15 minutes. That was interesting I thought, so...

In the table below I have listed the in-cylinder lengths at 6 inHg at the end of each session.
I have included continuous sessions where the pressure mostly has been at 6 inHg, but not over that pressure.
I have not included longer sessions that had a pause in the middle.

For the people who like to measure in inches:
cm 19,8 19,9 20,0 20,1 20,2 20,3 20,4 20,5
inches 7.80 7.83 7.87 7.91 7.95 7.99 8.03 8.07

* NOTES for week 35 *

* Monday: Jelq, 180 strokes (90 reps) during 15 minutes. Then uli 4x45 seconds.
* Tuesday: Pump, 15 minutes at 6 inHg. 20,4 cm (8.03 in) in-cylinder length at 6 inHg. First 2.5 minutes at 7 inHg.
* Wednesday: Pump, 10 minutes at 6 inHg. 20,4 cm (8.03 in) in-cylinder length.
* Thursday: Pump, 15 minutes at 6 inHg. 20,5 cm (8.07 in) in-cylinder length.
* Friday: Pump, 10 minutes at 6 inHg. 20,4 cm (8.03 in) in-cylinder length at 6 inHg. First 2 minutes at 7 inHg.

Remark: 4 mm has been added to all in-cylinder measurements since they have been done with an extra latex sleeve mounted on the cylinder. This adjustment gives values consistent with measurements made before this extra sleeve was mounted.
