The bone press...

[AdmiralLongDong]

Bone pressed always leaves me confused. I mean if I jam it in there I'm 8 and 1/4 or close to that. If I don't I'm 7.5"

How much pressure on a bone press?

What's more exciting to me is the newly acquired 6" mid girth. Definitely cemented.

I suppose I have reached my long term P.E. goals at this point. I've got an 8x6!

I'd say it's like using Q-tips in yer ears; push till you hear the CRUNCH then back out 'bout a half inch.
Or, just press till it hurts.
The whole idea behind BP measurements is consistency.

Exactly. You want to push the ruler firmly against the center of the pubic bone and measure to the tip. Be sure you measure exactly the same every time so you will not be guessing when you make gains.
