How, precisely, in the absence of the higher input rate previous poster
mentioned do you propose this piece of magic happens???

Duration of input.

??? Longer on at constant input -- higher input, certainly, but that
comes at essentially higher setpoint. Has nothing whatsoever to do w/
the rate of recover (or loss).

From a given starting temperature, at 'cold soak' the rate of transfer
from the heated air to the structure is identical at a given temperature
irregardless of the thermostat setting as long as it is above the
setpoint (again, w/o a source of 'aux' heat). The heat transfer rate
from the air to the structure is simply a function of the temperature
differential and the operational characteristics of the heat source are
no different.

You can turn it on in the morning after the setback at 72F or 90F and
the recovery is identical (again, w/o a source of 'aux' heat). Anything
else is simply perception.
