Are these facts true??????

And yet another one:

6) Partial true.
It's true that tracer bullet has different aerodinamics, weight and penetration ability (tracer won't penetrate even regular helmet from 200m) but not that much to make 80% missing during shooting. During WWII average distance of air conbat was 200-400 meters (often closer but rare farther) so ballictics difference doesn't afeect much in this distances. So 20% accuracy was not the result of tracer ballistic but the result of WWII air combat's nature itself. It's quite hard to hit anything moving at 400 km/h 200 meters from you while you're moving at 400 km/h yourself.
