*** Phew Wins ***
Case closed. :')
If you want case closed, that is fine.
Your calculation for Phew have no indication that the value produced is the ratio of a circle's circumference to its diameter.
Instead, the value you have is merely 6-2*sqrt(2)=3.1715728752538099023966225515806.
This has no connection to pi, and not really any connection to circles either.
So all you have is a made up formula with no connection to circles at all.
Conversely, you have been provided with a derivation of pi, based upon circles, showing what the correct value is (or limits of it anyway).
This is an ironclad connection to circles and thus is a real formula with a real justification, with definite calculations.
So pi wins.
No matter how much you want to pretend it doesn't, no matter how much you want to pretend your delusional nonsense does; pi wins.
The only way to make it so pi doesn't win is to show the derivation of pi is wrong. Point out what step of the 60 is wrong, with an explanation of why you think it is wrong.
Until you do so, pi wins.
The only way to make it so your delusional nonsense wins is if you can provide a derivation of it which links to C/D. A formula with a random bunch of numbers isn't enough.
Now grow up and either provide an explanation of why some point in the derivation is wrong, specifically applying to a single point, or run away and never return.
