What you say is possible, but I suspect that the power is running full when applied to the resistors during the on time. During the off time it most likely is opened to them.
Someone needs to understand exactly what the pf reading means with this meter when the power is interrupted at a low rate duty cycle. In other words, what readings are shown for the current----are they the true RMS averaged over many power cycles or the RMS when power is being applied to the resistor? How does the duty cycle affect the numbers shown? At this point in time there are too many questions and not enough answers. It would be wonderful if the testers would clarify these reading since I suspect that they have a lot of important facts that were not published. Andrew, you need to do some of this research yourself since you seem to be the guy that questions everyone's measurements. It is easy to throw darts at another but why not make yourself a target on occasion? And, you remind me of MY since you keep repeating mainly the same issue. If you really seek the truth, offer good suggestions instead of attacking without the proper information. Anyone that would seriously suggest that high voltage was being snuck into the system is not being honest. And, if RF were being sent at this high level into the resistors, there is little chance that the meter readings would not go wild with position which would be obvious to the testers.

IIRC the box uses triacs. These take a chunk of each power sine and pass it on to the load. The chunk has to start after a zero crossing, and continue all the way to the next crossing. If the power desired is low; the delay is long, the current pulse (seen by the wall plug) is short and the phase of the current must trail the phase of the voltage. By some good fraction of 90 deg. If the box contains a power oscillator (perhaps needed by the waveform spec) to feed the triac, than this does not apply.
