For God's sake, please stop beating this dead horse!  The average
upright player piano that requires rubber tubing for the tracker bar
uses less than 200 feet of tube -- 'nough said.  Thirty years of doing
players and I never even thought once about estimating the amount of
tubing I was going to use on any upright player or even grands for that
matter.  I don't know how many listings of this question have been
posted so far but there are _far_ too many.  Some folks have got a lot
of time on their hands.
