Froome sounds like a very sincere guy...and there is no evidence so he should be left alone (although you could say that about Lance, aside from the anecdotal tidal wave). But I would not be at all surprised at any pro rider cheating including those at Team Sky. Its not just Lance, history tells us that most exceptional performances in last 10 years have been dodgy. As for appearing human in later stages rather than super doper strong... an alternative theory could be that Team Sky had pushed their luck, got the margin needed, and were calculating to keep a low profile. Of course there could be something other than pure hard and effective training that gave Froome the edge in that stage. It could be legal (or not illegal), and in which case why would he/ Team Sky share it. Great Tour anyway. I fear for Quintana that he may have missed his chance this year, what with no solo Time Trial.
