Since Toby notes he fired the savage 35000 times or so I think it possible that he double loaded the powder. I work in evaluating incidents and with high repetitions there are always mistakes that the mistakee swears could not have happened. He is a true story. We had trouble with personnel putting the wrong hazard labels or missing a label on outgoing shipments. We instituted that the sign installer take Poloride pictures of each side of the truck for the record. A truck was stopped with no signs installed and the installer was told. The installer swore he installed the proper signs and said lets go look at the pictures I took. As you guessed the pictures he took of the signs showed that all four signs were not put on the truck. It is very common in high repetition work to make incredibly unbelievable mistakes that you just know you could not have made.
