Thanks a lot, that reduces considerably the discrepancy.
Also, I found a 2006 note of mine where i wrote (assumed?) that his total weight (with bike, etc) was 76 kg not 78 kg.

karlboss said:We've made an error, the finish isn't in the traditional place, and by google maps it's 8.1km from the pedestrian crossing at the roundabout to the finishline. Elevation gain is 644.
Using the same numbers as yours, but the variations stated gives
393 watts+2.5% = 403watts
403/67=6w/kg
karlboss said:LeBreton, I've no problems with what you did. You used the numbers you found and had been quoted, they disagreed with what Parullo had which was it was a little over 8km, then you used 8700m. I thought well there's a huge descrepancy there. Looked it up on climb by bike 8.7km and that noted where the finish was, then looked up the tour de suisse finishing town map, and the finish location is quite different.
On my point about wind, you'll note I was referring to Costa, who as far as I know did not ride Joux Plane, but Verbier. It was a general point, but if you know the wind conditions on Verbier you'd no doubt include it.
Roundabout, the schedule doesn't add up with google and I doubt google is as far out as it appears. There is a gap between 8.9 Villette-Le Châble to le cotterg 8.1 is about 800m, but le cotterg to Rue de Crêta-Cô is 6.8km, whereas by the schedule it should be 7.5km. However Rue de Crêta-Cô is 600m from the finish. I think someone has been lazy in assuming the verbier climb is 8700 and done the directions at the bottom using that, and then at the top using where the actual finish is.

Why didn't you say so? instead of making me waste time trying to clear things? Really annoying
karlboss said:Le Breton, Halamala, and Parrulo. Where did you get your time for the climb?
I make it 21:00 from the pedestrian crossing at the round about to the finish. Using this videoThey cross on about 7:20 and finish at 28:20.
BigBoat said:hmmm......
halamala appears to have the average power of Costa just about spot on. He's a tad off Wiggin's probably average power in this time trial where Danny Pate was "smoked" after averaging over 5.7 w/kg for 21 mins.
To beat the top contenders requires almost exactly 6.4 w/kg over a 60 minute period at the moment.

jens_attacks said:the start is the same portoleau used in 2009.he says that the carrefour le chable-route de verbier is at 8,5 km to go.the finish was the same in 2009 and this year.
in 2008,the finish was different,they stopped higher.
