That 1g per 1 lb of bodyweight began as 1g per 1kg of lean body weight, somehow became total bodyweight, and then mixed Imperial with Commie, so we're at 4x the amount of protonz as they originally planned. Is it all a scheme by Big Proton? Maybe.
At one time I learned what they consider the wall thickness to bore diameter ratio of a safe blackpowder device to be and marble : conduit definitely isn't it. But there are also people shooting bowling balls out of gas cannisters who to my knowledge are still alive so who knows.
