Stuart solved the discrepancy. I use a standard bicycle pressure meter which shows the absolute pressure - not the pressure relative to the atmosphere that he was talking about. My cartilage is still fine. I am not the first one to talk about this. Adolf Scherbaum mentioned it on one of his records back in the 70s. The quote was that he could inflate the tires on his Citroen limousine. Some of us thought that based on his sound, that he would be better off working at the gas station. That was a pretty stupid take though. He was one of the pioneers in picc trumpet playing and leveled out the road for many that came after him.
