No question there is that the cycling technique is dramatically improved. using the old calibration James is consistently seeing 40% increase in output with less effort. It is extremely likely that he is not producing less than this actually. This is near certainly correct. But at the old calibration the RPM is half.
If James sets the calibration so that the rpm is correct then the human output numbers are doubled, James just saw sustained 280 human W while conducting a several mile 5% grade climb.
He has inquired of the experts in Vancouver help to resolve the disparity. Both settings are credible. It is most conceivable that James has been All the time in Mount Whitney Lone Pine registering half of what he was actually doing.
