Yes, the actual powering up of the member accounts is done on the 6th week. Until then, Steem power equivalent to the SBD that would otherwise be powered up that week for the person, is only delegated. This is to guard against the possibility that someone, say the first beneficiary, after being powered up, decides to opt out of the group.

Otherwise I am glad you endorse it. It is still a loose idea, still open to fine-tuning, and especially getting a 'benefactor' to dispense the role laid out in the post.

Thanks Big!
