I've known a few providers who have, over time, improved their looks through a combination of: dieting (One who actually looked better after gaining a few pounds.), working out, better hair styling and use of makeup.  And of course, let's not forget about the marvel of bio-engineering (implants, lipposuction, and plastic surgery).  Mental attitude also is a big factor in looks.  If you agree that the face is the primary thing with which we judge beauty (I know that this is not the case for all men.), and if you agree that the smile is probably the most important aspect of the face (the eyes a close second), then if a woman's attitude is improved by her enjoyment and familiarity with the profession (as opposed to lacking that at the beginning of her career), then that can also account for the improvement of scores.

As women see the financial gain of adapting these measures, one would expect to see improvement in scores.

Still to go from an average of 6 to 7,up to a 9 to 10, is a bit of a stretch, but not impossible.

One other possibility is that as a woman's performance improves, the hobbyist is likely to view her physical appearance as also better.  It's just a natural psychological reaction.

or just not review her if she didnt do anything lookswise so as not to hurt her business.  this is what guys have said on the boards anyway.  also to see  guys who give out 8,9s  etc, you have to have someone give you an 8,9 to get the ball rolling.....

One other thing to consider is the evolution of clients. Clients change over time and in a 2 years span I have seen a difference in clients so therefore providing a difference in taste in what they consider beautiful

Re:Provider evolution??

Sometimes the parts equal more than the whole.  I have been with an experienced provider that on any given issue she was a 7 out of 10. Face, eyes, lips, tits, hips waist, grooming, you’d say was less than a 10. But, her attitude and charm and demeanor was a 20! Can a woman improve over time in both appearance and performance, absolutely!
