I agree that the numerical system, in its present form, lacks precision. However, I think the best way to add precision is simply to use the words that you suggest. In reviewing a club, it is well to make a few comments on those issues that other posters on this board put some stress on, even if they aren't important to you...for example, even if you don't care whether the dancers do extras, you might note whether they are available (though you may have turned them down when offered).
One area that I think defies quantification is atmosphere...some guys like showclubs, with glitzy surroundings and "glamour girl" types; others like places that are less pretentious (the phrase "Cheers with naked girls" comes to mind). Probably the only effective way to communicate which of the two paradigms a particular club fits into is to type it out, and damn the carpal tunnel syndrome!
