Nick Flyger, though I think he's now at AIS.

The signal-to-noise ratio in this thread makes it not worth following.

I don't know what they did for Project 96 but this particular analysis included not just order-dependent drag parameters but also a (simplified) renewal model that was order-dependent.

Right. It couldn't have been done with HRMs, or with just a wind tunnel alone. It was a very nice, very tricky, piece of analysis that relied on data from several tests with power meters in various ways. Canada won bronze by the narrowest of margins.

That was a very cool and tricky piece of analysis.

Testing is good. This isn't quite true. I reported the average over a particular loop or lap (not ride) because that's typically the smallest contained unit of complete information riders have. However, if you have complete information for shorter intervals then you can compute the drag over...

Perhaps, but I'm pretty sure I once described to you how I grade student homework problems: I read until I find the first mistake then I mark it wrong and move on. In your case I rarely read past the first sentence or two before I move on.

I get slightly lower Crr (.0067) and slightly higher CdA (.377), but the Crr *is* high: it's my commuter bike with the heavy tires. As usual, Frank didn't understand the moral(s) of the story: 1) varying your speed across laps or loops or test runs improves the estimation, and the wider the...

Well, power is pretty variable, especially in races but even sometimes just when doing normal on-the-road training. That makes mean wattage a poor estimator of the overall workout or race stress. Andy developed NP as a step in a bigger picture way of quantifying stress by intensity and "exposure...

It's not the "equivalent energy expenditure" because that would just be the number of joules. If the original quote had used the word "physiological" rather than "psychological" then it would have been pretty close. The Bannister who developed TRIMP was Eric W. Bannister, the physiologist...

Yeah, but sometimes you can still interesting patterns. Like: 2003 Worlds: 2004 Vuelta: 2005 TdF: 2006 TdF: There are others, as I'm sure you're aware.

Oh dear. Your history sounds like mine, although I never had a Look MaxOne. My bete noire was the original PowerTap Prolog. Anyone who knows me knows how ironic it was that I should have the only power meter whose data was not downloadable. After Whitt & Wilson came out, guys quickly coded the...

Hmmm. I've been doing estimates of power during various climbs for longer than Vayer, and irritating the self-avowed accusers of dopers. Now that actual power files are being published for stages, it's (occasionally) possible to makes estimates of "virtual" wind experienced by riders during...

His weight and bike were the same, though I don't know if his wheels were the same. I know the race tactics he used both years -- and whether he hid better or he had more beneficial winds, the point is the same: his VAM was 6% different but his watts/kg wasn't. It wasn't the Telegraphe but it...

I have data on a rider who did the same uphill race two years in a row. The second race was 6% faster, so his VAM was 6% higher. However, unlike all of these cases, I also happen to have his SRM files from both years, contemporaneous accounts of the conditions, and his comments on race situation...
