Oh yes, the rating is unfair because [USER=7161]@petricor[/USER] is not in the first place 
It's a joke. To put it seriously, the rating is really unfair cause we have performance ^ 2 (performance*performance) in the numerator and volume ^ 1.5 in the denominator. So, performance has more weight than volume. The fair formula, in my opinion, should look like <performance>^1/<volume>^1 (performance per liter). For example: (Multipier1*<GPU score> + Multipier2*<CPU score>) /<Volume>. Or separate ratings for GPU and CPU: <CPU score>/<Volume> and <GPU score>/<Volume>
For example, gamers have simple formulas
<Average FPS> / <Price> or <Performance> / <Watt>
rather than something like this:
<FPS in game1>*<FPS in game 2>/ Dollar ^ 1.5
or
<Performance1>*<Performance2>*<Performance3>/ Watt ^ 2

So, we need 6 more entries and go for round 5
