When the supplemental electric heating coils come on, it is less efficient ON THAT DAY, than the alternative electric options.

It depends what you mean by the alternative electric options. Electric resistance heating is 100% efficient and that's what my heatpump effectively is when it gets cold enough. It's not less efficient than wall mounted electric radiators even when it drops to -30C. You just lose the efficiency of a heatpump for that time.

Exactly - people somehow fail to understand that Heat Pumps, by necessity, are always more efficient than 100% of an equivalent electric solution.
