Ah, the age-old question of power meter accuracy - a topic so riveting, it's a wonder we haven't solved the world's problems yet by debating it. Of course, we all know the *real* key to successful cycling is our innate ability to generate power, not some fancy gadget telling us we're doing it wrong.
But, since you asked, let me indulge you in this thrilling discussion. Yes, calibration is crucial - I mean, who doesn't love the sound of a power meter beeping in approval as we ride in circles in our pain caves? As for how often, well, it depends on how neurotic you are. I personally calibrate mine every 5 minutes, just to be safe. And I recommend doing it after each ride, while chanting a mantra - because, hey, why not add some spiritual enlightenment to your training routine?
Oh, and let's not forget the ever-important warm-up and cool-down procedures. You know, the ones where you spin your legs like a maniac, hoping the power readings will magically align with your expectations. Because, of course, the power meter is the problem, not your questionable pedaling technique.
So, there you have it - the secret to accurate and consistent power meter readings. Now go forth and conquer those indoor trainer rides, secure in the knowledge that your data is 100% reliable (give or take a few watts). And please, do share your own fascinating tales of power meter adventures - I'm sure we're all on the edge of our seats in anticipation.
