Jun 13	comment	Is there a simple way to measure, record, and use wind resistance or tail winds? Very nice. Two small correction: in part 2, air resistance varies with the square of air speed. Therefore, the power needed to overcome that air resistance approximately varies with the cube of speed (actually, (ground speed)*(air speed)^2 ). And, wind doesn't alway cancel out over the same route. Wind often has a pattern determined by geography and season, and wind speeds follow a Weibull distribution so, for example, you can end up with more extreme headwinds in the afternoon than tailwinds in the morning.

Jun 10	comment	Is there a simple way to measure, record, and use wind resistance or tail winds? Actually, we can measure all of those individual factors. However, measuring them all is either hard or expensive, and the OP's question was whether "there is a simple way" to do this. I was struggling with a way to write a simple response to a simple question but your short response is superior to the long (and growing) answer I was working on so I'm going to upvote yours and abort mine.
Jun 9	comment	Is there a simple way to measure, record, and use wind resistance or tail winds? There are, but they're of limited usefulness because you'd then need to "subtract" your ground speed from the indicated air speed to get the net speed of the wind. But since you're mostly interested in accounting for the wind speed in order to get a better sense of performance gains, there are other ways to measure that. I'll work on an answer.
Jun 8	comment	Is there a simple way to measure, record, and use wind resistance or tail winds? Is your question about measuring wind, or is it really about measuring performance improvements in the presence of wind that confounds the measurement? That is, there are anemometers that can measure and record wind but that's not particularly a bicycle-specific question.
