The aircraft that is shoot at don't care about muzzle enegrgy, what he cares is the damage he is about to receive. A bullet that has, say, 20% more muzzle energy is bound to make a hole in aircraft skinning, slightly better than a the bullet with lower muzzle energy. If a weapon system indeed 'spits' more energy than another system, but the effect on target is smaller, that there is no point in boasting with that.
I'll concur that 37mm shell was far heavier than 23mm, but they were both fired at same velocity, so the disparity in trajectories to 300-400 yds ought to be minimal. I don't see why should be hit by 37mm, 400 rps gun, regarded as remote possibility.
