Ratings are totally subjective.  If she wasn't a 10 to you...that settles it.

Greek is one of the four, and only 3 are required.

"For performance ratings, it is asked that you please save the 8, 9, and 10 ranks for situations where out of the ordinary services are provided (i.e. Blow Job - without condom, Kissing - with tongue, Anal - Yes, and Really Bi - Yes). Of course, the 10 rating should be reserved for an experience that is really worth a million!

An escort provider is only eligible to earn up to a 7, unless she is willing to perform one or some of the following during a session: Kisses With Tongue, Bare-Back Blow Job, Really Bi, and Anal Sex. For each of these services that are offered, her potential max score is raised by one point, with 10 as an absolute maximum.

This does not mean she earns extra points for offering these service(s); just that she is now eligible for a higher score. Her maximum eligible score is based on what is offered, not what is performed during your session with her. You may or may not be interested in the extra services she offers, but the fact she offers them makes her eligible for the higher score."

Re: What would be the criteria for a provider to earn a 10.

A 10 is once in a lifetime, right? How many once in a lifetimes are there? I haven't given a 10 out yet although I've had some spectacular sessions. I only plan on giving out a 10 once. Sorry ladies, but I think that a 8 or 9 should make just about anybody happy.

TER's guidelines require certain activities - DFK, BBBJ, Greek, really bi - in order for a provider to be ELIGIBLE for a 10. The keyword is eligible. Even if she does provide all menu items necessary, if she isn't a 10 in your books, she isn't a 10. Plain and simple.

Frankly, I think its tacky that she would make an issue of it. A 9 is an excellent score in itself. Its kind of hard for you to forget its a service, if you have to defend your review score to her.

As far as being too hard as a reviewer, definitely not. Some argue that a guy should only give out one 10 ever, because you can't really have two "once in a lifetime" experiences. I don't think a 10 should be that jealously guarded, but even still, giving out a 10 should mean that she fit YOUR definition of perfection, and in theory, that shouldn't be something that happens very often.

In order to get a 10, the playdate must include DFK, BBBJ, and either be a double (two ladies), or she must include Greek.  Technically, if any of these elements are missing, TER Admin can adjust your rating downward if you overgrade.  Also, if there were elements about your session that didn't exceed expectations, you shouldn't cave to pressure from the lady.  Writing reviews is done as a service to your fellow hobbyists, as well as the ladies.  Would you as a hobbyist appreciate it if other hobbyists inflated their ratings rather than being truthful about ladies you might be considering seeing?  Didn't think so...

One of the most common causes of score inflation is subtle intimidation from a venal or delusional provider.

EVEN if Greek or Doubles is had; rating it as a "Once in a lifetime" experience is up to YOU!!
