According to the author (on other articles) 470 Watts seems to be a
physiological maximum on a several minutes effort, WITH an exogene
helper. i.e EPO, autotransfusion...anything trendy.

A "human" maxi with no help being arround 420W.

The reason xc skiers are such max O2 freaks are supposed to be because
they use every major muscle group in the body, and this allows the total
energy output to be significantly higher than for a bike rider where the
upper body is (mostly) dead weight.

As I've written here a few times, it seems like activities where you can
vary the load across multiple muscle areas allow higher total energy
output than something like bike riding or track running.

I.e. world class orienteers maintain a higher percentage of their max
heart rate than marathon runners, and xc skiers would seem to be
similar. (The main difference being that xc skiers do get some rest
periods on the downhills, where orienteers stay close to max heart load
all the time.)

Bike calculation are easier as friction is well measurable. On steep
uphills aero interaction is minimized.

Right.
