Or Wiggins grossly underperformed in Copenhagen (wasn't his average power ~10% lower than normal, or am I thinking of some other race where he averaged only ~400 W).
Wiggins in ITTs 2011:
Paris-Nice, stage 6: 2nd (+20" from Tony Martin over 27km)
Critérium International, stage 3: 2nd (+4" from Andreas Klöden over 7km)
Tour de Romandie, prologue: 77th (+12" from Jonathan Castroviejo over 2,9km)
Tour de Romandie, stage 4: 4th (+18" from Dave Zabriskie over 20,1km)
Bayern-Rundfahrt, stage 4: 1st (33" up on Fabian Cancellara over 26km)
Dauphiné, prologue: 3rd (+6" from Lars Boom over 5,5km)
Dauphiné, stage 3: 2nd (+11" from Tony Martin over 42,5km)
Vuelta a España, stage 10: 3rd (+1'22 from Tony Martin over 47km)
World Championships: 2nd (+1'15 from Tony Martin over 46,4km)
While the two ITTs in September see Martin making bigger time gaps over everybody else, Wiggins also beat Cancellara by the same margin in each, so it would seem that Martin's performance is the yardstick there rather than Wiggins'. I find it hard to see either as an underperformance, as I see them as a comparatively fair reflection of Wiggins' capabilities at the time (bearing in mind that he was returning from a collarbone injury at the time too). He was consistently a top 3-4 competitor, but was also consistently beaten by Tony Martin. The margins he held over the rest of the competition were very small compared to the margins he was powering out over everybody except his own teammate time trialing with his spindly legs akimbo.
Wiggins, aesthetically speaking, is about as good as it gets in terms of time trial position. But there was a clear step up in his capabilities 2008 to 2009 as he went from specialising in prologues and short-to-mid-length TTs to being a guy who can compete over all lengths and terrains, and there was also another one 2011 to 2012. It was exacerbated by comparative underperformance from Cancellara and especially Martin - but the margins he was pulling out on people compared to where he'd been the previous year speak of a significant improvement in his time trialing capabilities.
