Randomized surfing

You could potentially still win with 33%. That hit rate is fairly high against top bots such as DrussGT or Diamond(in my experience). You could still beat sitting duck, since you gain energy every time you hit. And sitting duck does not shoot, so you will still get 100%

You will do well against top bots(assuming you have good movement) with a 33% hitrate. You will do well against sitting duck with 33%. But you may not get such a good score against average bots since 33% is okay, the enemy may have a higher hitrate.
