My ratings are "relative", i.e. a comparison of semi girls to each other. So if I say a girl is 4 stars, that doesn't mean she's a DDG model but just how she compares relative to other semi girls. And keep in mind we all have different tastes too, this is just my subjective rating.
Also, in my first couple of years of hobbying, I wasn't aware of this site so it was mainly just hit and miss. After I discovered this site, I mainly saw girls that were discussed and reviewed on here or was recommended by guys in PM...this helped to eliminate any truly bad experiences.
I'm not saying my 90% will DFK with just anyone...for most, it will depend on your connection with her.
