You can't flout them and expect TER to let your scores stand. Asking "for a specific kind of performance" and being given it will not be found in the guidelines.
Please read the guidelines again:
"8.In order to keep our overall performance ratings consistent, we set up the following system: An escort provider is only eligible to earn up to a 7, unless she performs one or some of the following during a session: Kisses With Tongue, Bare-Back Blow Job, Really Bi, Anal Sex, or More than One Guy. For each of these services that are performed, her potential max score is raised by one point, with 10 as an absolute maximum. Remember, it’s your review; within these guidelines you still get to decide what her score should be. You do not have to give her the ‘extra point’."

Yes. I did!

And many other posts over the years.

The services offered objectively determine the maximum possible score = Y (usually, 7, 8, 9, or 10). The  
subjective quality of the services received determines the raw score = X (anywhere from 0 to Y, max).

Many of us have experienced some fantastic 7-out-of-7s and 8-out-of-8s and enjoyed them more than a lackluster 7-out-of-10.
