because it is included list of services in the "escort-site" template that many use. Take those lists with a grain of salt, since the escort effectively has to opt out of items by deleting them. How many are going to say no they're only "3 or 4 star" at best?

But with no reviews to speak of, I certainly could care less that "she" thinks she is 5 star talent.

I've never seen a "definition" of this..and I doubt you will find one either (except if you want to make up your own).

to me 5 star means a super attractive classy women that make you forget its a service versus the women who are all about wham bam thank you mam and are not so attractive.
i suppose that the review rating system helps differ the higher  end girls and the lower end girls kinda like how hotels have different star levels.

experience orgasms like the pharoahs!  you can count on me, cuz i'm a five star john!

I don't think there's an official definition.  A lady or service can describe herself/itself in whatever manner pleases them.  Though I do think the use of cliches like "upscale" and "5 star" indicate that they're probably not as exclusive as they make themselves out to be.

Well reviewed providers...  is the answer.  If you see unreviewed providers, you are in uncharted waters.  I seldom TOFTT these days.  My hobby funds & schedule are too limited to waste either.

... but 5-Star girls wear slightly better shoes.

I am not a fan of shoes on the furniture; what happens on the furniture is what's important... and those activities are pretty much identical.

However, I feel chemistry is more important than shoes.

Hope this helps,
