I'm not sure what you are asking but I only have used power, first a cordless drill with a cup hook engaging a paperclip attached to the end of the leader - furled for ~ 2 1/2 minutes or until it shortened the original length by 10% and then reversed it for ~600 revolutions or 45 seconds ot so. I now use a corded drill as the power is more consistent throughout the furling process.

p.s. When you furl too much the leader breaks and you start over. Good practice.
