Thanks for writing this, you set out these ideas so well. It's a really useful (and heartening) way of thinking about things. I've just done a little report on growth in the needleworkmonday community and, although, it's quite small numbers, the rate of growth (or return) is very good. The smallest accounts increased by 60% overall, thanks to a small amount of delegation to each of them, and the corresponding growth on the delegation was about 23%. Not that that benefitted the delegator, but it was interesting to illustrate the value of sharing around some SP. I think there are some other similar models.
