If I could inject a little of my perspective on recognition of future gains.
I never paid much attention to my flaccid condition. I don’t mean to say that I wasn’t happy with the increase in flaccid hang but I didn’t put any thought into expecting erect gains from a flaccid condition.
What I did find that was extremely accurate and futuristic was my ligament length while hanging. What I did of course was to hang SO. While in that condition it was easy to put a ruler over the top of the hanger and while making sure that the anchor point on my pelvic bone was the same every time, I could see changes over time to my stretched ligament length. It is a very accurate measurement as it is extremely consistent.
Now the reason I came to depend on that measurement to be the indicator of erect length gains is because in general there are so many variations and factors that affect erect length measurement. Much depends on your blood pressure, your overall feelings that day, whether or not you’ve been watching any porno and even the time of day can have a effect. There was too much variations from one day to the next.
What I found was on a day to day basis the stretched ligament length was very consistent.
I mentioned above that keeping the same anchor point on the pelvis was important because if it varied from on point to another it would affect the total length measurement and it was easy to cheat on yourself if you changed the point it would indicate greater length when in actuality the increment was not as great so beware. :-)
