There's an inconsistency here.

TER's system of rating for performance tends to be objective, so they set the rule -- not always enforced -- that a provider must offer certain services in order to be rated above a 7.

However, if we want to score based on the reviewer's experience, then it should NOT be called performance. I am all for scoring subjectively, as in appearance.

In your example, a blaring TV and the condition of the room is the provider's responsibility. A knock at the door is probably not. For example, if a reviewer is spooked by seeing a black SUV in the front of the hotel, whose fault is that?

My point in the original post is that if the reviewer says "through no fault of her own", then why fault her in lowering the score. He could always describe his total experience in the narrative. It is a matter of fairness.

I remember the "5 senses" post, except that there are more than 5 senses.

" you read the first one or two and know what she does and how she is, the rest is like a bad re-run."

Not necessarily so. I have seen providers that performance went up after time, with me, and other reviews I have read. There are plenty of cases where she was covered BJ at first and now she is BBBJ. Other performance enhancing techniques are also documented in reviews.
One of my favs would not allow COB when we first met, and now she has no problem doing snowballs, and if I drool some on her breasts, she rubs it in.
I imagine the reverse is also true in cases of bad hobbyist burn out,her performance would go down after time.
I usually read all the reviews unless she has page after page, and then I read the earliest and the latest.

I usually read a few reviews if I'm trying to evaluate a possible companion. The very first review which usually yields the parameters of which services are available and description of the porovider. Then I often go to someone who has given a lower than usual score and compare to other reviews that particular reviewer has given. If there are any gals in someones list that I have also seen I'll check out for comparisons sake. You have to try to get an idea of what the reviewers are looking for. Anal for me is inconsequential since I'm just not that interested but multiple pops are important for me as well as time management. In the final analysis it's a guessing game with a few clues from the reviews. By the way Personally I'm more inclined to the GFE than PSE. Scores tend to be all over the place and have to be evaluated in terms of the reviewer's individual scale.
