If I measure from the side I`m 7 1/2” !

I`ve always measured from the top, pressed or not, and so subsequently I`m around 6 1/2” bpel right now, but occasionally i gain another 3/8” (!?!)

I measured after a clamping session recently and even though I wasn`t completely erect I measured 6 7/8”. I was standing up, which might have been a factor, and I`ve never done so before or since.
