Moving up past 85 APS -- Not Easy

So I've put a lot of time in on XanderCat, what is supposed to be version 12. Wow is it hard to improve at this point. I had roughly 10 new ideas for improving and all of them had no positive effect. The only improvement so far has been in some refactoring I have done, which has simplified a few things, but not changed my score any. There are a few instances of robots that some other top competitors score nearly perfect against, but XanderCat only gets maybe 85 or 90. I think I may figure out how to make some improvements by closely scrutinizing those instances. I also want to take a closer look at each of my special case scenarios to ensure none of them are counter productive -- this includes my ram escape scenario, anti-mirror scenario, my targeting detector drive engagement scenario, and my bullet shielding protected gun wrapper. I don't expect to find anything wrong though; probably will just be verifying that they work as intended. Ho hum...what next...it seems like there should be some big gains to be had, given XanderCat is still 5 APS behind the leader, but darned if I can find them. I'll keep trying when I have the time though...
