37% of what? equal what? did I miss the suggested number? I see that it's dependent on the number of people that you are considering, from 10 to 100, but that leaves a difference of between 4 and 40 people to date. How do we know how many people, total, we would date, when we are just starting?

I get the feeling that this article only has half the math.

As an aside, I've heard that the optimum number for this equation is in fact 12. So 12 is the 38%. But this article doesn't confirm that - as far as I can tell.
