Im Glad i found this thread.
My starting BPEL is 7". I am now on my 3rd week of JP 90 day beginner routine.
So of course i measured to see if by any chance any "growth" has occurred. Now i measure a little shy of 7" (perhaps 6.8"). after reading this I'm going to blame EQ.
Hopefully no more loosing length business.
I am in my late 40's and due to my current relationship (wife not very sexual) my EQ has declined. I remembered in my 30's when sleeping around my dick would get so hard it hurt i would get to 7.5" and this is why I started PE. to get back those hard erections and get to 8" or maybe even 9" ? (wishful thinking...)
Neededless to say the advise to follow here is to stay off the ruler.
