Second to last time, I got it right AT the 6 week mark.
With paypal, you can cash in right up to the last day of one month (let's say October), and it will be paid at the end of the following month (so, end of November). You can certainly cash out before the end of the month, but unless you're not going to earn *anything* between then and the end of that month, there's really no point to do it, just wait to the end, and then you have just approx 4 weeks to wait for it to be in your paypal account.
