0.6 update

Yeah, between 3000 and 4000 battles it dipped from just above to a little ways below. My testing is fairly minimal. I do a few battles with some HOF, some Shiz, some DoctorBob, a sample bot and a top bot, just to check I haven't broken anything major and that the changes made some sort of difference, but I haven't had time to do any proper testing. I'm still at a stage of adding major features, once I get on to tweaking the testing will be more important I think.

In future I'll wait for 4000 battles before making any conclusions... sigh.
