Who among us tracks the accuracy of Manual J?

Who among us tracks the accuracy of Manual J?I have hour meters on maybe 20 systems now.    I like to see the run time when it's "4" degrees in Kansas City.  99% rate in KC is +4' degrees.  My goal at 4' is 100% run time.   I have a super sealed home 2,100 square feet  with a 2 ton ground type heat pump R-30 walls, R-60 attic, R-8 windows & doors with 98% run time @ "+ 4' ".  When the strip heat turned on, it smelled up the home with the dirt  off the 5 KW strip, heat burned off the dust.  …See More
