The following is an extract from the FAQ portion of the Reviews section.
"Again, please try to save the 8 and 9 ranks for situations where out of the ordinary services are provided (i.e. Blow Job - without condom, Kissing with tongue, Really Bi, More than one guy). Each of these, beyond-the-call-of-duty talents count for one hard earned point. Of course, the 10 rating should be reserved for an experience that is really worth a million!..." and "Ratings above 7 are reserved for providers who render services that are considered to be real perks (i.e. Anal, BBBJ, Kissing with Tongue)."
If you are following these guidelines for posting a review the only services rendered during a session should be considered in the rating. Simply having the service on the menu shouldn't constitute a higher rating. I recently had an exceptional session by all rights should have been a 10 and stated so within my review. But holding firm to the guidelines I rated it a 9, my fault not hers. I know I'm preaching to the choir here and don’t mean to sound like the Delphi Oracle. Set me straight if need be.
