It's likely not algebraic at all, they're likely using one of many sorting algorithms that take "hotness" into account, which is to say, the time between reviews is a factor in the total score and likely how new the provider is as well.
Does anyone know what the formula for the determination is? I had went through and calculated it based off of what I currently see on the list, which would make it a=appearance score, b=performance score, c=total number of reviews, r=overall ranking score. Obviously a higher number of reviews weighs more overall, so that would seem to make the formula (a+b)/c=r, but that formula seems to leave several people that should be on that list off. So I have the formula wrong, or is it just not being updated often? Any math wonks have input?
will weigh in and let us know.
I wouldn't sweat it too much; on the surface, it seems that 9 is simply the new 10 for performance if your score is above 7 and you choose not to blow out your anus.
I'm sure there is a more sophisticated way to say that...

Just how, I have no idea.
...stars for location and chemistry from the beta version are messing with the ratings regarding Top 100 lists because TER has some formula for that. But that is only effecting ladies that have reviews done using the beta version. Also a provider has to have a review within the last 3 months or they aren't on a Top list no matter what their average is.
...It should be because it would seem to be more difficult to maintain a high scoring average over 100 reviews as compared to the minimum requirement of 20.
I think TER takes the average of the Appearance score and the average of the Performance scores and averages those two to come up with the scores for the Top 100.
Number of reviews had nothing to do with it. (Except for the 20 minimum) . This is why most of the Providers way up at the top had fewer reviews. It's a lot easier to have twenty 10/10s than one hundred 10/10s.
The recent change involves beta reviews with the chemistry and location ratings.

In your equation, as the number of reviews (c) increases, the ranking (r) would go down. (And not in the good way.) so that's why that's not working if you'd want more reviews to lead to a higher score.
I doubt TER is accounting for number of reviews, but possibly. The world may never know.
As xyz said, the new chemistry and incall scores are effecting the ratings, but we don't know how exactly that's being computed.
Both chemistry (call that H) and incall (I) are 1 to five stars, for a total possible of ten. I looked at one profile with both H and I scores and tried to get to the overall rating listed. With just a slight bit of rounding error, it looked like they may be combining H and I as a new X out of ten parameter and then averaging across the three.
That would be [a+b+(H+I)]/3=r
The ()'s around H and I aren't mathematically necessary, but there for clarity.
I can't say this is what TER is doing, but on the one score I checked, it's possible. WAY too small a sample to try to claim it's been reverse engineered.
The incall score is not required, so a provider could have an H but no I, which would mean they're getting screwed over if this theory is correct. (And not in the good way.) In a case like that, maybe they double the H, to try to make up for the missing I. So in the equation above, the (H+I) would become (HH).
Or maybe this is all crap. Who knows?
Also, if you're checking the math and just looking at who's on the list or not, remember what someone here said about minimum number of reviews and at least one review in the last 90 days to even be eligible. I think you'd do better to just stick to the names on the list and try to get them in the right order with your math.
Actually, TBH, I think you'd do better to drop it. Don't get obsessed, just be you.
I'm not sure why you want to know. I think you may need to find a way to be okay with never knowing. Good luck.
So is it still 5 reviews before a gal gets a star rating?
Also, how am I supposed to rate location? Close Proximity or she comes to me gets a 5?
I was thinking it funny that this one gal gets stars for chemistry after one review but no overall star rating: https://www.theeroticreview.com/reviews/kate-ferris-324548
The overall stars system, the one that is displayed at the top of a profile, and in lists (like if you had done a search and you're looking at the results page): that's supposed to represent her overall score. Yes, for those to show up she has to have a minimum number of reviews. I believe it is 5, but I'm not 100% positive about that.
The "chemistry" and "incall" stars are different. They're relatively new. If anyone has filled out a review for her on the "new" TER, they will have put a value for those, so they will be there even if she has just one review as you noted. Totally different star system. It's basically two new areas for grading. The looks and performance are 1-10, chemistry and incall are 1-5... stars. Just to complicate this further, the chemistry and incall scores are factored into the overall scores, but I don't know for sure how they are calculating that.
You asked how you should rate the incall. When these two new scores were introduced by admin, they gave a brief explanation of them. I didn't put a link to it because I don't remember where they put it and it's not in the review guidelines where it belongs. It was really brief and vague as I recall anyways. So, I can tell you only what I do, this is my opinion. You could always leave a feedback with admin asking for clarification.
If I did an outcall, I'd leave it blank. She didn't provide the location. For an incall, did it feel discrete and safe enough for you? Was it tidy or was it a dump? Was a shower offered, and if so, appropriate necessities available? It's just your opinion of the space and maybe a little of her hostess efforts. No big deal. IMO, it has nothing to do with proximity to me.
This thread is sort of buried and this is all just my own opinion. You might ask over on the newbie board. You'll get more good viewpoints and I'm willing to bet someone will have a link to the descriptions of the chemistry and incall.
no serious math formula. Simple average of looks and performance scores, and only providers with 20 or more reviews, and a review within the last 3 months are eligible.
However, as a couple posters mentioned above, the new chemistry and location stars have some effect now. No idea how TER figures it into the equation.
