I think an Instant Powerdown should cost 20%, not 5%.
And I'm saying that from someone who would actually use it.
Instant versus 13 weeks can easily double the gains that a person would achieve at the peak of the bull run.
NOTE: Instant Power Downs should only be considered after the savings feature has been improved to allow longer holding times of up to 13 weeks.
