I think alot of the "highly reviewed" "excellent reviews on TER" are marketing ploys. I've seen a lady claim "Voted Best on TER" despite having no profile... and I've seen ladies with multiple 10/10 reviews downplay the reviews as well.

Different strokes for different folks.

Speaking for myself as a hobbyist, I've come to rely more on personal interaction with the ladies i meet at the various meet n greets and other social events as opposed to just scanning the database for companionship.

I'm no longer the guy looking to fuck the flavor of the week. It's the intangibles. The chemistry, the connection, can she stimulate me intellectually as well as physically? These are the things that make for an excellent, and repeatable encounter for me.

But to give you a specific answer, if raw numerical data is what you seek, for ME the answer is an average of 18 or better.

chemistry is all important. But if we don't get to the events we rely on the reviews of our fellow hobbyists, and if there is no chemistry the first time, there is no second time. "Highly reviewed" doesn't mean high reviews. One could have a lot of reviews but not high reviews, 8 -10.

which would more appropriately be stated "highly scored", I look for 8 or higher PERFORMANCE averages.  That is what I consider high scores.

As for looks, I don't base as much on that, because someone can have a certain look and that is fine for me.

You do realize that the performance rating is based on services performed, right:

In other words, if you do not do any of the extras on that list, you at best can get a 7.
