That's pretty interesting. You can definitely squeeze some points out of rammers, but for me that was more a matter of personal pride / fun than really going for APS. My bullet power, distancing, and kernel density formulas had a surprising amount of room for improvement even after Diamond was at #2

On wall hits, I'm curious how that turns out for you. Dookious and Diamond hit walls sometimes in 1v1. In Melee, Diamond uses precise prediction to never choose a movement option that would hit the wall in the next few ticks, and the result is a really smooth and nice and beautiful Melee wall smoothing that never hits walls but really hugs them. I tried applying this same logic to my 1v1 movement to avoid all wall hits, and it was a super huge pain to get it all working right, and then I gained no points from it. So I removed all the mess and just left it at hitting some walls sometimes.

As a thought on avoiding false positives in mirror detection, I'm pretty happy with the margin of error calculation setup I use in my flattener enablement. Basically, the hit % threshold I use to enable the flattener has a margin of error added to it, so I only enable it if I have 95% confidence that the enemy's "true" hit % is over that threshold. Maybe you could do similar and be really conservative in your detection early on and gradually get more aggressive as the battle goes on and you gather more data. I'm not sure how that will hold up with multi-mode bots but it's definitely something I'd explore.

Sorry to double post, but on the wall hits, consider: if you can slam into the wall at full speed and take a bunch of wall hit damage and it's your best chance to avoid a HOT or linear targeting shot, do you really want to rule it out as an option? Hitting the wall doesn't cost you score unless you lose a round, but taking some bullet damage costs you a lot of % score against such a bot.

Not enough battles to know for sure yet, but looks to me like eliminating hitting the wall will only have a very marginal impact on score. Version 11.8 is currently showing only 0.05 APS better than 11.7.2, despite hitting walls only about 1/3 as often. Oh well. On to the next possible improvement. I'd really like to get a solid lead over Hydra.
