Indeed, I was in error focusing on the load. The shunts were measured correctly with the probes.
That 5 (or now 7) MHz signal being displayed by the scope is noise. These scopes use the highest available voltage peaks of the wave form to calculate period and frequency. Clearly that is not the frequency of the timer nor the load resonance. It may in fact be resulting from wire ringing.
The term "ambient" should not be confused with "baseline". The 25 Celsius stated is your baseline resistor temperature, not the ambient temperature of the experiment's surroundings.
The ceramic resistors' baseline temperature in an un-powered state will most likely be several degrees below the ambient temperature surrounding the experiment.
