Might give that a try myself with my next few days of staking then and see if I get similar results!
Just noticed your vanity HYP address by the way - veryyyyy nice!
Is there a nice easy way of doing that? I read about it a long time ago, but never got around to playing

I got my vanity address from iDunk on irc. So there is a little layer of security that is compromised, as it requires that I trust that he deleted my privkey. So I have been doing a little work on a setting to autoforward transactions of certain addresses, so this would mean it would only pass through the vanity address for a very short period of time, minimizing the 3rd party risk a little bit.
