I always thought the shaving was more to aid in medical attention to road rash, than actual aero affects?
Its both. I understand this is about TTs (racing) in the General forum, but that is what the OP asked about racing naked, and speed suits - ie being as fast as possible given the same (assumed) power. Keep hair out of the wind.
In the TT, places are often determined by seconds. Hair on legs slows you way down (could be several places) - even if covered the hair stick out and have some effect. Same with arms.
Then there is always the psychological thing. That is worth a whole bunch, but hard to quantify.
