I think the biggest concern of the original formula was, that builds under 1L kinda break it
the easiest solution is to prevent build volume values below <1 in the formula - so if we just use mm^3 instead of cm^3 all should be good and fair for all
my idea:

as example, I calculated some of the entries (where dimensions were given):
[USER=1085]@guryhwa[/USER] Rome Build: PPV = 313.856
[USER=7161]@petricor[/USER] Build: PPV = 230.230
[USER=2121]@chinevo[/USER] EM780 Build: PPV = 110.983
[USER=18145]@REVOCCASES[/USER] "BR1KY" Build: PPV = 100.368
[USER=22036]@articnova[/USER] P3 Tiny Build: PPV = 92.143
[USER=27015]@SFFMunkee[/USER] N0RDR1 Build: PPV = 23.735
if you just look at those builds without any calculation, the performance / size ratio looks more correct to me than previous formulas
anyway, it's just a idea - we can also keep using the original calculation or base it on [USER=37937]@Steven[/USER] 's idea - but no matter what we agree on, we should prevent <1 values
