According to 7 day trending curation numbers from steemwhales.com, my bot outvotes me consistently. And believe me, I've tried to beat it. It's also a little interesting that the two often seem to rise and fall together, although that's probably not too surprising since my goal with the bot is to create an approximation of my own voting preferences. Hopefully, the similar tracking means that I've managed to achieve that (to some degree). The gaps are a few days where I didn't have time to collect numbers.
