From my viewing you have wasted an awful lot of time on this and you have proven nothing.
Take for example your third highest ranked girl by this method with a mean of 19 should be a cracker except when you look you see 30 reviews 10 of which are ratted positives 2 negatives a neutral and 2 n/a
this girl has a mean nearly twice the level of the girl in your other thread Alyssa I know which I would go an see.
