Fair enough.
Honestly speaking I have always worked with the 10-20% increase numbers, so I was surprised with the 40% increase statement. Of course we have to take into account that cyclists might not be the best mathematicians
. Having said that, I have always thought that the gap could be greater than 20% for the third week of the Tour when you factor in the recuperation percentage. But this is just an opinion. So that's why I wanted to read more about other studies related with these numbers (although it would be very hard to find unless you do these studies with cyclists actually riding the GT's, and we all know how clean they are).
Thanks for the opinion.
