Melee Gun Thrashing

I think the trouble is if there is say a peak at 3*PI/4, and another at 7*PI/8, and both are almost of the same likelihood, then even though the gun can easily turn to both, if they keep changing which is better then I might never end up shooting. Now, as soon as I have a single tick which the best angle changed less than MAX_GUN_TURN_RADIANS, I will fire next turn. Although it seems I have lost some score with this version, so maybe it was better before??? I know I need to do some serious work on my gun, it matches vs all the top bots I get much lower bullet damage.
