Tangible I PM'd you but should have posted here for everyone;
Are PayPal payouts scheduled at a certain time of day, or on as-needed basis?
We pay PayPal and Dwolla in batches. There is no set schedule but generally we pay about 6 to 10 times per day between 8AM and 2AM (unlike the blockchain and Satoshi's ghost we occasionally do sleep

). "Usually" that works out to within 2 to 3 hours although due to scheduling conflicts it can occasionally be longer than that.
