Gaining BPEL not NBPEL

Is there a current theory as to why some gain “bone pressed length” but not “non-bone pressed length?”

Soflsun,

The only theory that I can think of is that if you are gaining bpel and not npbel, then not only are you gaining length, but you are also gaining weight.

I can not think of any other reason why you would gain bpel with a corresponding gain in nbpel.

With tight skin the lengthening of the shaft might pull the skin forward right at the base where you measure

Duke,

I’d go along with that.
