I assume you mean me, (since I'm the only person with any calculation in this thread)?
I based my calculation on elementary mathematics.
Let's say there are 100 payout requests a day.
They pay 30% of all requests each day.
On day one, you have 100 requests, and you pay 30.
On day two, you have 170 requests, and you pay 51.
On day three, you have 219 requests, and you pay 65.
On day four, you have 254 requests, and you pay 76.
On day five, you have 278 requests, and you pay 83.
Assuming you clear the queue completely, say, once a month or two, nobody waits more than three working days.
