According to my estimates after the hardfork the average annual curation ROI is just above 7% (assuming everybody votes optimally). Right now the return that I am seeing is 10% to 11% which is much less than the 18% to 20% that I was making before the change.
I guess it all depends on how efficient your curation patterns were before the hardfork (from a maximazing point of view).
Exactly, I am reaching 11%, before I was reaching 8 or 9% but, as I said, I upvote many comments which, before, did not use to get me so high efficiency at that time.
