Interesting, your approach seems to work pretty good. I noticed that you are using pretty low upvote weights. How is your bot selecting posts ? Are you using user submitted posts or artificial intelligence techniques?
My bot is at 93% efficiency right now. But I never trained it to identify high value posts. Just high quality ones. So just from that an efficiency of 93% is pretty decent.
For that I'm using traditional machine learning and NLP techniques ( just a simple Latent semantic analysis combined with a random forest). I'll upgrade those techniques with state of the art language models etc soon, but for now that's my approach.
