Quintana is right at 6 W/kg.

Porte is right at 6.2 W/kg.

These numbers for a similar workout tell me more. Not to mention if in the calculations for Quintana they took into account the drafting in most of the ascent.

Yes, Portoleau took drafting into account according to the Chronoswatts reference (113) :

Sa puissance moyenne estimée est de 6,2 w/kg

en considérant qu'il était pendant 80% de temps abrité dans les roues pour profiter d'un léger « drafting » en côte à 22 km/h (30% de réduction des résistances aérodynamiques). La puissance étalon du « coureur témoin » de 78kg avec vélo se situe à 422 watts (+/- 3%).

Portoleau reduced the aero factor by 30% for the 80% fraction of the ascent during which Quintana was "drafting".

The 6.2 W/kg correspond to a 70 kg cyclist. As Quintana is considerably lighter, redoing the calculation with his actual weight would presumably increase that 6.2 figure to 6.3 or 6.4 W/kg. However, since the uncertainty is 3% according to Portoleau, we have 6.2=6.3=6.4
