Geoff Vadar said:Show me some evidence that your gains are unobtainable without the use of a powermeter. Your gains come about primarily from your application of training philosophy (or that of your coach).
That is a bit of a strawman argument, as the powermeter greatly aided in the "application of the training philosophy".
Geoff Vadar said:A powermeter adds "efficiency of application" of your chosen training philosophy. It also adds intelligent feedback for coaches spending significant time planning detailed training schedules for elite athletes.
However the gains in "efficiency of application" over and above training governed by "perceived effort" would not be significant for hack middle aged C/D grade (Cat3/4/5) athletes.
Furthermore the intelligent feedback loop would be utterly under utilized by coaches in prescribing training to hack C/D (Cat3/4/5) because they simply wouldn't pay the coach enough to bother to "farm" the data.
That might be true where you live, but here in the US there are plenty of coaches who charge very little for their services, but spend plenty of time "farming" the data.
In any case, it seems that your criticism is really aimed at (what you perceive to be) the cost of good coaching, and not at powermeters.
Quoted post said:So stop bringing me your 'look at my overall improvement' data and trying to lay it at the feet of your powermeters. That's [censored] and you know it. And Andy knows it.
Actually, I don't "know it". That is, I figure that the world can be divided into three camps:
1) those who figure out the best* way to train based on trial-and-error;
2) those who figure out the best way to train based on feedback from other people (and/or devices); and
3) those who never really figure out the best way to train.
What I think powermeters (and, IMO to a lesser extent, watches, speedometers, heart rate monitors, and blood lactate analyzers) tend to do is "speed up the learning curve", so there are fewer people in group 3, and more in group 2.
*Recognizing, of course, that "best" is a very broad category.
Quoted post said:Which brings me back to my original argument. They are overpriced to be realistic for club cyclists. If you can get a cheap one use it. If they want you pay $3000 tell them to stick it where the sun don't shine.
A powermeter is worth whatever someone is willing to pay for one - period.

Remind us again of your background in the sport? ;-)
