About the accuracy of the models. On the Tour, Portoleau goes to the major cols to measure the wind etc... So when the conditions are "standard" the best models can be very accurate ... if you know the weight.Parker said:SRM and Powertap only claim 1.5-2% accuracy, so anyone claiming that their estimates are 2% accurate is just straight up talking crap - especially as some of the variables - e.g. weight, wind (which varies) are not measured at source.
Anyway, it's not the numbers that are important - but what he then does with them.
About the accuracy of the SRM : how do you think SRM and Powertap measured their 1,5-2% accuracy ? how do you think Schoberer the guy who invented srm validated his work ? One realistic answer: he's used some models (to calculate his estimates as you call them) in lab conditions.
However the SRMs, Powertaps etc... are not certified so you can't be 100% sure of the measures on a given equipment. Same thing with the log files sent by the riders you can't be 100% sure they are accurate.
So EVERYBODY, including the ones using power-captors, is talking about power data with error margins.
Vayer is using his estimates to underline that only dopers have been able to achieve a level of performance similar Froomey's performance in Oman (btw it's also superior to Froomey's perf in Ax 3 Domaines last July).
So Vayer says Froome is doping. I think Froome is very suspicious (the "very" because of his background).
