If MOST women are rejecting you, there is a problem.
I own a business. We both sell things and provide a service. People call all day asking about prices. I like to set my prices where I get 85-90% of those customers.
If I get less, there is a problem with either the price point or product for that price point. If I get 100%, my price point is to low and I can do better, so I simply increase the price points.
You should apply the same to dating. If you are getting rejected 90% of the time, you are either hitting up chicks way out of your league (consistently) or you need to do some serious work on yourself (frame, game, looks, social circles, etc).
On the flip side, if you are never getting rejected, its time to start hitting up hotter chicks.
