Yes a little anticlimactic after yesterday. But I think Pog can take easily another minute here. At an average 24km/h the climb itself would take about 20 minutes. Vingo's goal must be not to get caught.
In theory gaps in this TT should be moderate (short climb, fresh effort) but after yesterday it seems Pog has a big advantage (and can take 1 minute as you say). I can imagine that Vingo can limit his loss to 30-40 seconds if he's better than yesterday.
