70% efficiency! That is fantastic! It's still hit and miss for me. Sometimes 80% on a post and sometimes 35%. 

I'm also still getting used to HF21. I have a decent amount of stake and it's an improvement for me over what I had to do before to get ROI. 

I do think the dust still has to settle. And I do feel that these improvements might be better for Steem as a blockchain (As a whole) but it will mighty differ per individual how they feel about it.
