Thanks for the delegation comparisons. In your example Smartsteem was paying about 38% APR simple interest. Correct me if I am wrong, I believe Smartsteem delegation returns are variable. If you have evidence of their historical delegation APR I would appreciate it.

Is there a calculator or some other way to estimate the vote selling rewards? From other readings it seems like curation rewards are about 15% of the post value (I think themarkymark provided that data). Although the individual curation ratio would be impossible to predict I suppose. I wonder what percentage the last up voter receives in curation rewards.

Additionally, I can not find any information on how the vote selling values SBD. Is it variable based on current market rates or is it always static at $1. Steem really needs to get rid of SBD if the price will not be maintained at $1... just adds some much complication to every operation.
