  Thank you for finding that. It really is fascinating. Mind you most of the numbers need updating :-) U.S. 50. %tile weight is now 194.7 lb not 161.9 lb and I suspect that the 97.5 %tile is even worse (but a cursory search didn't find any data).

  Amazing - thanks. I thought the reliability statistics for the different dial types was fascinating.
