Hahaha stolen !! Just kidding, of course you can copy, i'm glad that my stat tab is interesting !
For volume I've taken an easy solution. cylinder volume. It's surface area of the girth x lenght
V = Ag x L = Pi x r² x L
Pause. Next i use the girth value to obtain the average radius of your penis.
Girth = 2 x Pi x r
So r = Girth / ( 2 x Pi )
come back to : V = Ag x L = Pi x r² x L
So, we have : V = Pi x (Girth/2Pi)² X L
which is : Volume of your cock = 3.1416 x [Girth/(2/3,1416)]² x Lenght
Excel formule is :
=3,1415927*POWER([Girth cell of your tab]/(2*3,1415927);2)*[lenght cell of your tab]
For your tab, it seems that, for example, for your start erect volume, using your BPenis EnlargementL and girth mid in inch, you have :
=3,1415927*POWER(B5/(2*3,1415927);2)*B6
Change cell value for cm.
You can steal it !!
For progress, i'll explain later,; my system compare the 3 volumes - start, current and goal.
