When I was in my mid-20s to mid-30s, I traveled a lot for work, made good money, and had access to generous company expense account. I was still decent looking (had a strong resemblance to a soap opera star of the time that even young women seemed to know and like), so I had some game with civvies. So, when I was out of town my MO for an evening was to hit a good pickup bar/restaurant and see if I could score that way. My standards were usually a little lower than for P4P girls and given my age would bag a cougar on a fairly regular basis - a skill developed when I was 19 and 20 in college and the 30+ singles would flock to my favorite dance club on a Friday or Saturday night. If I was paying a $20 cover and $8 a drink (a fortune compared to $5 cover and nickel beer on the off peak nights), I was gonna fuck SOMEONE that night.
Anyway, that established a pattern where I was perfectly happy with 5-7 in the looks department as long as I found a 9-10 in the sex department.
During my peak escort mongering years, I spent a king's ransom a couple times for a 10 or a 10+ and ALWAYS ended up disappointed with the sex. Girls with 10+ looks and GPS never have to learn to turn a guy on with their sexuality, so they are quite often bad in bed.
So, today, when I no longer have youth or looks for civvie game (well, I do get attention from civvies but it's because they are hoping I might be willing to upgrade to Wife 2.0, which ain't happening since I have Wife 1.0 configured just the way I want it), I apply same principle in P4P world. I focus on 5-7s for reliable, mature, regular, affordable NSA sex (SA has been working well for me, but I have had to separate from 2 that developed the SB-to-MRS virus) and I'll take a flyer every now and then on hot stripper OTC, of which I'm now 2.4 out of 5 (I rate one a .4 success cause we started good but crashed and burned, and there was never a visit without complications; and one of the other 2 may not really count cause she's pretty much a full time escort now). The good sabermatric is that my "ITC spending before first OTC" has gone down dramatically.
And, finally, if I'm craving a 10 there's this super hot FBSM girl in town. FS isn't available, and CBJs are overpriced (although I did indulge once and it was one of few times I came from a CBJ), but damn just getting to see, play with, and kiss her gorgeous body and get a massage and a HJ from her is worth the price.
