That's true, Bob. But my avionics (Sierra Flight Systems EFIS) allow for the 
presentation of wind direction and velocity. I merely fly into the wind, and 
then downwind, eliminating the need for three legs. BTW, its better to do 
this test in calm conditions, and at 2,500' AGL.  
My results tend to confirm what I see on my screen in flight, so will rely on 
the EFIS in the future.
I input a lot of PIREPS to Seattle Flight Watch on 135.92 on my flights in 
and out of the Puget Sound. Wind direction and velocity, corrected OAT, and 
flight conditions are the main items on my PIREPS.
This Sierra system is really fantastic.!!
