Averaging the 2 non-anomalous readings is bad, it introduces instability to the equation. With 3 readings we are counting on only one being bad, if 2 are bad, it will return the bad average anyway.

The plan that I had proposed would return the least anomalous of the last 2 readings.

If we need a larger sample to average, it would take a bit more code and variable space and we would merely make a average of 10 (Slower 'instant' readings at low speed) or running average of the last 10 (Instant update, lagging by 5 values). IMO, this would bypass the entire 'instant' reading idea. both also introduce errors at low speeds.
