That sounds like a pretty good and well thought out strategy. I guess I am far more subjective with mine... on any given day, I'm all over the map between 10% and 100% upvotes on posts, and 1% and (usually) 60% on comments.
One of the things I like about the new rewards curve is that it allows for a wider range of voting weight that still "makes a difference." So far-- even when I get a little too enthusiastic--I haven't yet had my voting power drop below 75%.
I'm going to try a strategy that I started last night but placed on hold until my vote strength is back to 100%.
Since I've turned off SteemVoter I'm trying to spend a few hours a day curating and commenting and I usually upvote a minimum of 20 posts a day. This hardfork has really put a crimp in my style.
