Would you prefer 1 10 or 5 2’s?
For my own standards, a woman has got to be at least 5 in looks, but then offers a 9-10 in some kind of special service. How about this for an algorithm:
Sum total of Looks + Service = 15+ with no individual score below 5
Taylor is 5 Looks + 10 service = 15
Yaya is 7 Looks + 9 Service = 16
Barbie is 8 Looks + 8 Service = 16
Understood that both Looks and Service are subjective. Unfortunately, we've probably all had too many <15 totals. I've had knockouts that were horrible, and even worse, some fuglies that didn't deliver in service either (worst case scenario). For the OP, if Taylor was subjectively a 2 in Looks, then there's no amount of Service that can get him to 15+, and he should've just asked for his money back and walked at that point.
TBH, I can't remember the last time I had a 18+. I'm not a high roller, so I don't dabble in that $400+ range where the 18-20 score can be possible. I miss the old days where the KMPs were the standard, and you could easily get a 8+ Looks with 8+ Service for $200. But, BBBJ and other GFE Service was pretty rare. These days, with the cost considerations, I have to be choosy where I find the value, probably playing in the 14 - 17 range with some missteps drifting into the 12-13 range.
Edit: I think the last 19 score I had might've been Nina from Thai Silk. Legitimate 9 Looks, 10 Service for $240. Miss her.
The last 18 I had was probably Abby at New Rainbow. 9 Looks, 9 Service.
