In a case like this I see increased self voting as a long term strategy to gain more steem power you otherwise couldn't get.
I'm on my phone so I can't see the charts, but don't be apologetic if your self voting increased. It's a wise thing to do with this gift. The more steem power you can gain through it, the more you can share the wealth in the long run.
looking at the numbers again, I'm realizing that pre-delegation I gave away $20 and gave $1 to myself. post delegation I gave out $65 and kept $4 for myself
all in all, I gave away $40 more than I did before the delegation
I'm not good at math, but when I look at it that way, I feel like we all won!
