Try to think a little bit before you write, it's annoying to tray to explain everything, as if to a child: B-26 or TBF have no problem at all shooting down damn slow, flammable Kates and Vals, while the P-38 and SBD-3 shoot down Zeroes, which have little or no 20 mm ammo left after fighting Wildcats in Midway. Even if a Zero with little or no 20 mm ammo happens to go for a B-26, it will encounter serious fire, a resilient target and a P-38 or TBD.3 on its tail, so the Zero is much more likely to lose than to win the fight. P-38 had 150 rounds of 20 mm and 2,000 rounds of .50 cal and it takes a few rounds of either to light up a Zero. Zeroes had 120 20 mm rounds (for two guns) and 1,000 7.7 mm roounds (little use against American planes and) and they are fighting Widcats in Midway (which can absorb a lot of rounds), and Zeroes in the CAP are trying to shoot down even tougher B-26, P-3, TBF and SBD. Too bad your list of lost planes does not specify the SBD-3 which had to ditch for lack of fuel or because Yorktown was damaged and those lost to friendly fire or accidents. Somehow, you concluded that a small IJN CAP and even fewer planes attacking piecemeal only Yorktown had wiped them out.
