The beginning of Risoul climb was a quite low slope (6%), ridden at 28km/h behind a AG2R team-mate. Consequently, the estimation cannot be done on this section (too much drafting).
The choosen section starts in Risoul, and ends at the finish line.
Majka's performance couldn't be measured on that section. But it was possible on a shorter section while he was alone (9.66 km, 25'42", 426W, 6.2W/kg), perfect analysis conditions.
For the full climb (from Guillestre), the times are (+/-5s) 31'50 for Nibali-Peraud, and 32'15 for Pinot, Bardet, Van Garderen and Majka

Where do these data come from ?
Frédéric Portoleau, our "Watts expert" is doing all the power calculations. He started his times and watts measurements in 1988. The details of his work are available here.
Several chronos on the website have been measured by Vetooo, a finnish cycling fan. You can follow his activity on twitter here.
The threshold definition is done by Antoine Vayer.
"Not Normal ?", the magazine, has been created by Antoine Vayer, Stéphane Huby and Frédéric Portoleau.
Finally, the website is the work of ChronosWatts.com team
