This was the thinking behind the race to up-armour fighters in the ETO; would also apply in the PTO. if you're both unarmoured, and both have roughly equivalent planes:
>you jump enemy, or enemy jumps you
it's up to pilot aiming; one well-aimed pass and you're toast
>you both are aware of each other, and you dogfight
it's up to pilot manoeuvring skill or deflection shooting
however, if your fighter is armoured, and the enemy's isn't:
>enemy jumps you
you stand a good chance of taking it on the seat armour, and either running for home, or dogfighting the enemy
>you jump enemy
if you don't hit, you can try to escape / reposition and even if the enemy hits you, you might survive
>you both are aware of each other, and you dogfight
you have the option, EVEN IF the enemy is more agile, of turning to face the enemy head-on
you can force a duel of armour and guns with an advantage; you have armour, the other guy doesn't; you can take a few hits on the chin but he can't
this option is particularly important fighting the Zero / Nate, since the Allied machine-guns effectively outranged the underpowered Jap 20mm, and you might even have De Wilde incendiary ammo or Hispano 20mm which gives you an even greater edge
even if you get hit by a 20mm, it might not kill your plane outright. the rear armour might absorb some of the hit and leave you merely wounded, not dead. the shell might blow up an empty fuel tank and leave you with a crater in the fuselage you can fall through, instead of the entire plane in flames. you stand a slim chance, of getting home or converting, which you don't have without protection. it's slim but
