Bullet Detect

Yes, that's correct. I found it helped my stop-n-go a lot doing it this way, and the <=3 didn't have any effect on score. Also, don't worry about ramming because if they are ramming then they are too close for stop-n-go =)And wall hits would be nice to take into account, but I'm afraid they are a tough nut to crack even in mega, never mind in micro :-/

Yeah, I've found using onBulletHit adjustment instead of limiting the energy drop to be much more effective against linear targeting, because if the enemy fires the same tick the bot hits it, or the same tick it hits a wall, or even the same tick it gets a bullet hit bonus, its fire will not be detected. If you have some codesize to spare, I would also recommend adjusting the enemy energy variable on onHitByBullet, to make it even more accurate.
