I know what your saying, but unless I misinterpreted, the author was lamenting how most of his 150 first dates were a waste of his time. so that's where he has to decide. 150 dates with potentially little bite, or maybe 10 (or less?) dates where his worries are almost guaranteed not to be an issue. Of course zero first dates is not good either. Given his interest in experimenting like this, I'd be curious to see if he did a follow up using the above strategy.
