Just wondering if anyone uses this as a measurement. I find it useful when compared to your regular BPEL. It's a good way to check your limiting factor.

Tonight I did some clamping and I was about 7.05" BPEL while clamped. After taking it off, I went down to about 6.75" BPEL. I'd say about 0.1" was due to my extra head swell however.
