Study cadence, not power.

Modeling cadence, speed, and heart rate over time (preferably every 1/2 second) can tell you 95% of what’s happening with you and your bike. Adding power data only gets you that extra 5%.

Power is gennerally used to monitor fatigue...or make numbers to brag about on forums

Max Speed and Average Speed are what determines who wins and who loses. Cadence is how you get there.

Keeping with the auto theme: Cadence is your tachometer. There exists a sweet spot.
