Note: towards the bottom they even have having an experiment that shows a good wax job lowers drag.

wax at low speeds may not have the same effects as wax at hi speed
but
there is some discussion on collector size and the effects as measured with transducers ...
outstanding , i like testing with pressure transducers
much food for thought
but
you could use the same concepts and measure over all back pressure with
water manometers , easily made by the DIY types
