I didnt read that thing but I ill say im all about aiming center mass, it gives you your best chance of getting hits if you are using any sort of automatic or burst type weapon, it also gives you the best chance at hits with a sight zeroed to somebody else and if you are using a rapid trigger squeeze with a semi auto just to get shots off you will have a better chance at connecting, like i said, i didnt read the article so if my reply doesnt go with the article then i apologize...
