Power outputs in mountain TTs/mountain top finishes has been dropping. 2007 was slower than 2006, and 2008 was slower than 2007 in terms of watts/kg that the riders where putting out. Having said that 2008 was a really hard course, 2007 much less so. 2006 was pretty tough course wise (not as hard as 08), but it was won by an E.T so you can expect rediculous watt/kg scores.
