Thanks, Carl! These are some interesting ideas for a follow-up :) The number of accounts and the growth over time is shown in a graph above. This network had author rewards of around 8 SBD + 10 SP in its last week before undelegation, plus a bit from involved accounts that have a few hundred own SP. The 160 SP after undelegation give a rough picture of the "lifetime earnings". Good point about the dust vote shift - living off hundreds of 15 SP accounts which suddenly have a vote "worth" only 13.8 SP per vote certainly makes a difference. However, the rewards in general changed quite considerably over the HF, so the plain numbers would probably give a biased picture there.
