I think you can't really blame sky for being dominant (I don't like them but thats something personal. Until last year I didnt like Contador too although races with him are often great to watch), better blame the UCI, because they have the chance to make rules which would make cycling more interesting again (like smaller teams)
If you scan down there are segments which give weighted average power over the section of road. If you go to analysis you can use the profile and left mouse button to choose your own sections to look at and get averages, max power etc. I tried to selected the whole of the final climb which gives me an average of 369w.
