Owned by a complete non sequitur, that if you get better each progressive year, that means you are clean. Of course that does not demonstrate that at all, and the devil is in the details. Linear progressions can be dirty, especially if you dope early, and a progression even in linear track can still be very suspicious. It matters nothing if you get faster year to year in a nice upward track if in the process you have a hugh upward swing or start running anamolous times. Sorry.
