I was thinking about something like, once a month you can take out 1/26th of your total SP instantly and if you were going to do a real power down immediately after then it would add 3 1/2 days to 7 days you receive the first payment.
I do agree that most people get in to situation where they need a small amount and not looking to power down the hole amount but need the money fast. I think something like this would solve that.
