When can I post my items now with managed payments??

Hmmm. My managed payments thingo is now active, and every sale I've had for the last 3 days says payment has been made, but funds are being held until cleared.

Ok, fine, but I'm used to receiving funds into my Paypal account and being able to post literally right away.

How long will it take for all these future payments to clear, and if it's 2-3 days, how am I supposed to maintain my account's postage and handling time of 1-2 days? I don't want to change it to 3-5 days just because of this! I like being quick for my customers!
