I said: "if Phi (or e?) would be a tiny little bit greater, then....
I didn't know otherwise till I found this week several internetsites which doubted the value of Pi !!!
For instance: Jain the mathemagics: "the true value of pi" ( = 3.144605512)

or
Panagiotis Stefanides (pi = 3.144605511)

Hassan Dinbali: pi = 3.15470053837925152901829756100955…

or
Mohammad-Reza Mehdinia "correct value of pi = 3.125
SO
if pi could be different what could that mean to my model and calculations?
Let's have a look:
classical PI = 3.14159265358979
PI = 3.141923949435...?
By the way:
600 is the surface of the sphere: 4 * pi * r^2
