@randowhale, I think random sleeping and awaking is not convenient for most users. How about opening few hours in the morning and afternoon with specific hours. Sleep most of night (How about sleep 8-10 hours in specific time to recover 3-4% vote would be better.). Though it will not mostly profitable for @randowhale but it will offer users time to use it conveniently. This algorithm sleep after VP drops to 98.4% will make very random and short, inconvenient.
