I don't know horning, but I bet if you and I worked together we could figure it out. If we really get stuck, I am sure mrfisher, who was kind enough to point out my “B” team’s work schedule, would be happy to lend a hand 
First of all let’s look at the rules. They are called the “GUIDELINES FOR SUBMITTING REVIEWS.” I found them very cleverly hidden on the page you must agree to in order to submit a review. http://www.theeroticreview.com/reviews/submitReview.asp
Item number 7 states:
“In order to keep our performance ratings consistent, we set up the following system: An escort provider may only eligible to earn up to a 7, unless she also willing to performs the following during a session: Kisses with Tongue, Bare-Back Blow Job, Really Bi, Anal Sex, or More than One Guy. The addition of each offering will raise the score she is eligible for by one point.
This does not mean she earns extra points for performing the service; just that she is now eligible for a higher score. Her maximum eligible score is based on what is offered, not what is taken. You may or may not be interested in the “extra” services she has, but the fact she offers them makes her eligible for the higher score.
If your review doesn’t already accurately reflect this rating system, we will adjust it.”
Let’s look at the first paragraph. “In order to keep our performance ratings consistent, we set up the following system: An escort provider may only eligible to earn up to a 7, unless she also willing to performs the following during a session: Kisses with Tongue, Bare-Back Blow Job, Really Bi, Anal Sex, or More than One Guy. The addition of each offering will raise the score she is eligible for by one point.”
According to the provider’s profile, out of the five extra services that can increase a provider’s potential score, this provider only offers “really bi.’ So this means that the maximum potential score she can get is an 8 (7+1=8).
Now I know your saying to yourself, “hey, why should she get an eight just because she has ‘really bi’ on her profile. She only did a lap dance.“ Looks like those sneaky guys over there at TER hid that answer in the second paragraph.
“This does not mean she earns extra points for performing the service; just that she is now eligible for a higher score. Her maximum eligible score is based on what is offered, not what is taken. You may or may not be interested in the “extra” services she has, but the fact she offers them makes her eligible for the higher score.”
After reading the instructions, it all is starting to make sense. TER only limits maximum scores based upon a limited menu. For example, suppose a reviewer only wanted the provider to dress up like ET and phone home. She did it exactly the way he wanted it, with the finger and everything, she should be able to get the maximum potential score she is eligible to receive. In this case it looks like a reviewer could give her a score from 1 to 8. He has to base her performance upon how he felt she performed the services he wanted, not how she performed the services that someone else may want. Looks like he decided out of a potential score of 1 to 8, she “Went the extra mile”
Thank you horning for your help finding about what’s going on behind the scenes. May I humbly suggest something that may help in the future? If you have any questions or believe that something is “messed up,” before you post about it on the General board of TER, first click on the FAQ button. There is one in every section of TER that will answer most, if not all of your questions. If that fails, we have contact us button on every page. Click and a kind and considerate support rep will try to answer your question as soon as possible. It may take just a bit of time based upon whether my “A” or “B” team is on, but we will get back to you.
We realize that there are other sites to choose from and we thank you for choosing to use TER.
Thank you for your support,
