I'm not the one focusing on one guy and his flawed estimates of power.
It's fairly easy to calculate the required power for climbs...and the equations to do so are readily available. Maybe you should see about confirming the physician's grasp of physics? After all, there are some posters on this very forum who have demonstrated that just because someone is trained as a physician, it doesn't mean that they have a good grasp of basic physics ;-) I'd put my money on Alex Simmons being able to give a better estimate of the power required than Dr. Ferrari.
To paraphrase Mr. Chung...my general impression is that mlinenb is a bit too quick to hit the "publish" button...
