Congratulations to all the winner and of course to Alan for the first place! The idea is great :)

As for prize pool - I think it is a good idea to delegate SP fr a period of time. But how much and for how long is up tot you. If it will be power generated by a certain post, or always the same amount. Maybe delegation to honorable mentions and keep the prize pool for the 3 winners (with some extra delegation or without)....
