Ok, upon a recalc (me dummy!!…) I found my error, now revised…

At 325w per hr, and a 75% duty cycle for 24 hrs = 244w (admittedly conservative numbers), watts convert to 19,968 btu/day.

Propane at 91,451 btu/gal / 19,968 = 4.58 days of refer operation per gallon…

5gal of propane x 4.58 days p/gal = 22.9 days of refer operation…

Sounds much more realistic (sorry for my bad)…
