My way of tracking length progress

This may not be a new idea for some people, but I thought I would share.

Basically I have a LeLux cylinder with a wide flange. I pump for 15 minutes or so and then set a ruler on the flange and measure the length. That length seems to be about 1 inch longer than my BPEL, but the exact difference doesn’t matter because I am only trying to track progress. If the pumped length increases a little bit then I believe the BPEL increased too.

The advantage for me is that the pumped length is very consistent whereas the BPEL varies greatly, so I can track the slow progress and feel some hope.

If you think it allows you to accurately measure and confirm mm level growth then it’s all good. That’s the main thing we need when measuring.

It does seem to be pretty consistent for me at least.
