I'll always look past an aberrant low score or two for a well-reviewed provider. Only when I see a number of 5s and 6s does it become a red flag for me.  

Providers do rate clients...

fortunately they don't get published.

Forget the numerical scores.  They are truly meaningless IMO as they are subjective.  Yes even Talon is correct when he sets his standards high as to what he feels a 10 is.  What's more important, to me at least, is a narrative that appears legit and paints a menu and experience and hopefully a hint at a personality that I may want to meet.

Side note...there is a way for providers to rate us btw...it happens when they check your references.  If you are really old, really young, really fat, really smelly, really aggressive, really rude, really psycho, and even if you are really nice that information is passed around plus more I'm sure.  It's the same as reviewers back channeling looking for the un-published 411.

I've seen a high end local companion here and she was great the 1st time but the 2nd time I guess she was jaded, maybe too many appts before me. I decided not to write a bad review for her as white knight here will think I probably have an axe to grind. I just let it go and everyone here will be happy.

...in gauging whether my money will be well spent with a Provider. If most reviewers have rated a lady between 8 to 10 on appearance, I find in nearly 100% of cases that I will rate her similarly. What a guy should ignore is the written description that accompanies a particular score. I see no reason to not rate a woman as a 9 for appearance simply because she wasn't tall. Once you free yourself from the verbage that TER has attached to the appearance scores, you'll experience the rush of being released from the judgement of the pedants who are really clueless. I'm most often on the high mileage end of the YMMV adage in part, I believe, because I've already done my research and already believe that the woman I'm going to see is beautiful and we're highly likely to have a great time.
