To clarify: If there is a partial payout (which is looking more and more likely) are you saying that all previous withdrawal requests will be canceled and account balances paid proportionally?
That would probably be the best method at this point, either way it goes. With the shutdown/default, the rest goes out the window and we're just looking at balance refunds at this point. Just going by outstanding balance across the board, seems like the best move to me. Less hassle overall.
