In the new AdMob interface, under Account -> Payments -> Payment Settings -> Schedule Payment, it says there is a $100 minimum. I heard from someone else that the minimum is actually $20 if you use PayPal, so I did some research to verify that and found this:

Is that $20 minimum accurate? And if so, why does it say $100 on the new AdMob site?
