searching for new provider in my area.  ran across a lady who has over 100 reviews.  95% give her a 10/10 rating.  the other five are  10/9.  does perfection exist ???

it is all based upon one's perspective.........and in the example you cite.........seems to be a very consistent perspective for the hobbyists who have visited her.

But by definition it's someone who by their appearance and actions stands out in a singular way, such that you may never again meet someone quite like her nor have that kind of experience.  That's how I think of 10/10 anyway.  

I've given two providers 10/10 scores. Both were as beautiful as any actress I've seen, and both were incredible performers, willing to do anything.

...it is definitely possible for a low-volume lady to "legitimately" have nothing but 10/10s.

I don't have many reviews because I'm very low volume and have a civvie job like the playmate the poster above mentioned. I was told you could not rate a 10 unless certain activities were given. Since I'm a bit more on the conservative side, the highest I can be rated is 9. :/

there is a huge fiasco going on  in Vegas the past months with a group of ladies (commonly referred to on TER as "the Group")  
and they have shill reviews all 10/10
in fact the number 1 provider here recently is such a girl who has only been around since december.
Theres at least a dozen other ladies involved.
