There were enough of them not to have to be watt-monsters. Andy was helped by only one man and only for some time.
Please, do not feel sory for me, it is not needed or appreciated.
Your logic is wrong. You accept that he lost time on climb (he did, only at he very end) but not on the false flat and into the wind against group of men killing themselves and against flatout Evans? Really?
The gap came down almost immediately and pretty quickly once Evans committed to the chase. He had done a few turns before in the valley and on the lower slopes, but only rolling through to try to get a paceline going. Once it was clear noone would help then he got on with it and did a great job - the gap fell very consistently from over 4 minutes until stabilising for a while at just over 3, then dropping quickly to 2.30 as Schleck struggled on the steep bit above the tunnel.
There were a few problems for the bunch:
1. They were deliberately waiting for helpers to come back up, they didn't push too hard on the descent because they assumed Andy would be slowish downhill and would give time for the dom's to reappear and do the donkey work chasing
2. The dom's that arrived weren't the right guys for the job and didn't have the gas to do it properly.
3. Voeckler was playing a brave tactic of refusing to put his guys to ride. It was a good tactic from him but it also made everyone else nervous of committing since they didn't really know how good Voeckler was or wasn't.
4. As seen at the end, Evans (and presumably Fränk) was the only one properly strong enough to make a worthwhile chase and he couldn't do it until he was confident enough that nobody else could and he had no choice in the matter
5. There may also have been a feeling that they wanted to leave Andy out there. The worst case was burying themselves to get Andy back and then Fränk taking off and getting a minute fairly easily. For Evans the ideal situation would have been to close Andy's gap to about 1 minute and then leave him out there - quite easy to miscalculate the chase in that situation - he had BMC riders there but he may have been telling them not to go too hard because Evans
wanted a biggish gap on the climb so he could put the hurt onto Basso, Cunego, Contador without actually quite catching Andy and giving Fränk the chance to go.
