Some do. But either way, first determining the most drag likely from waving puts parameters on the problem, which IMO is an essential first step.
I wave all the time with a twitch of 3 fingers. Sometimes a tiny jerk of the head. My impression is that no one notices. (if they don't notice, they'd have the same complaint about me not waving as if I hadn't, so we need a big wave here) You can test for the small waves if you want - but my intuition is that waving generally falls between the two extremes.
