After engaging in a number of daytime players (names witheld but the tactics should sound familiar), I've developed an interpretation of their dicta, simply by being shot in the face by them as I make my downhill attack run. Think of it as the Hand Dicta because it has five points, just like the fingers of your hand:
Dicta One: Always select a N1K2. It is the only Japanese airplane with four 20mm cannons and a good turn radius.
Dicta Two: Always press for the head-on assault. It is much preferable to aim with your guns than with your tail. If the enemy comes at you from any other direction than straight ahead, you should reduce your throttle and turn sharply into his attack so that you can use your four 20mm to outgun him. You do not need skill for this attack, so it is easy to learn.
Dicta Three: Do not engage in high-speed escapes. It is much better to follow Dicta Two instead.
Dicta Four: To engage attacks against ground vehicle, add bombs to your N1K2 and drop them on your target first, then you can strafe with your four 20mm cannons if you miss with your bombs.
Dicta Five: Play for the country with the greatest number of players and always patrol with at least 4 other players so that they can assist you by being the bait for the enemy attacks. Then, they can cover your escape while you land your victories. Do not worry about your teammates. You can get new ones. That is why you play for the country with the greatest number of players. Your wingmen are expendable.
