I believe op was using "dating" as an euphemism for "having sex with". That means dinner isn't required. Plus if the average unlucky guy has 1 date per 2 weeks, it would be entirely possible for a lucky guy to have 14x more dates. A 14:1 starting ratio leading to a 10:1 success ratio seems plausible to me.
