They probably go from 80 to 100% in going from 8 to 9. So its obvious that
thermal inertia would take it out about 2hrs.

We know that the 'Setting' is referring to the duty cycle, but we do not
know exactly what the relationship is. since 9 is the MAXimum setting, and
Lewan states 'power was at this point constantly switched on', then a
setting of '9' is presumably a 100% duty cycle. (?)
Since the PLC's are programmable, we cannot assume that a setting of '5' is
50% or 60%; it could even be programmed to be 10% duty cycle. So no useful
calculations OR conclusions can be made during this ramp-up phase.
Lewan did report that at setting "5" the "ON" and "OFF" times were equal.
So taking the duty cycle as PLC/9 is about as good as we can guess.
