To quote Cary Millsap (who, I believe quotes someone else) "you can't tell how
long something took by counting how often it occured". Trying to use any count
(lio, pio, BCHR, ...) as s substitute for elapsed time is misguided from the start.
Anyway, I think that this is the answer to the original question.
Thanks again!
