Thanks. Of the other 50%, where you had intention of continued relationship, what % did you realize the woman didn't have the same intentions before the sex and you still had sex with her?
If you are actually doing all this without results, I would suggest going out on weeknights. I don't know where you live but Fri and Sat nights are mostly "normal" women looking to have fun, not hooking up. Plus you will have more male competition. Women who are out on weeknights are typically more welcoming to hooking up, in fact, that might actually be their goal. Start with Tues and Wed nights. Forget Fri and Sat nights.
