Oh...and BTW - those that "know how to use the numbers" are a whole helluva lot like fit gurus. They have a way of approaching the numbers as a whole - looking at the athlete - and if they are good they can help a lot of people but not everyone.

It's like saddles, bars, shoes, etc. Everyone is different and everyone interfaces with the bike in a different way. Good coaches know how to work with you and learn what your body does and guide you through the process. If you're saying to yourself right now "I don't need a coach. That seems too extreme. Like too much." Then I question why use a power meter. Just because it's the next cool thing to buy and everyone has one? Are you really going to "use" it, or simply record it?
