Trying to use gyro theory and precession to explain rotor behaviour because it is easier to understand is exactly what has gone wrong in the past. The two are not the same yet in some countries, many pilots are told it is precession because the authorities think it is an easier way of explaining a complex subject. Every pilot in the British military, and a whole lot more across the world, are taught the aerodynamic explanation and understand it completely.
Offering the wrong explanation for something, just because it is easy to understand,
is not progress.
