On the shaving cream review ratings New York Shaving Company Tonsorial has a rating of 6.00 and The Gentleman's Refinary Black Ice has a rating of 10.00, but when you look at the actual reviews NYS Tonsorial has much higher numbers and nicer things said that Black Ice does. NYS Tonsorial seems like it would average out close to 8 and the number for Black ice would be significantly lower. What is the rating actually measuring?
