Congratulations on 100% PWin!

Well, DrussGT's random gun does take maximum reachable angles into account, which is probably 80% of wall effects. However there's probably something there about bots being hesitant to get closer to the enemy, even if they could potentially reach a further angle, which skews the distribution away from the reachable angles which are affected by walls. It would be interesting to do something with this hypothesis, but for me the random gun is really there as an emergency backup against someone simulating DrussGT's gun or something similar.
