thanks for the answer
anyone know how that (gunner) efficiency is affected in game? i'm guessing maybe its reload times? or/and is it more along the lines on how the AI handles the gun. personally I can't handle the flak

unless its those old slow propeller planes from the academy so I let the computer do it while I scan around with binoculaurs or just in F4 mode. OTOH the deck gun is a piece of cake (as many agree)
