The first is as you say, most of the bots are mis-rating right now but this situation will improve. The other issue is that I was watching a new player (lazy,0 and lazy,1) and this new player had a pretty high K value. So a further adjustment would be to limit the range of the K factors or even just use a single K factor if I am doing the provisional rating stuff. And of course I would only copy over ratings every 6 hours, after they are calculated.
