To play the devil's advocate:
If Mr. Armstrong is such an accomplished and medically/technically advanced doper, by working with the best of the best of the best (Sir), why would he publish his results online for everyone to scrutinize and discuss.
If he has the best team, then surely 'his medical experts' must have told him that certain, rather difficult to explain spikes, in the profile could show up, would show up and would eventually lead to public scrutiny in case he published them online.
1.1 The team exists, but didn't tell him or forgot to mention it to him
1.1.1 WHOOOPS
1.2 The team exist and did tell him
1.2.1 He ignored the advise, believing that if he stayed within the set UCI boundaries no one had anything against him.
1.2.2 He chose to weigh the pros and cons and assumed that the PR would outweigh public scrutiny. On top of that, staying within a bandwith would make it impossible in any case to get caught/convicted.
1.3 The team doesn't exist
1.3.1 Mr. Armstrong is convinced that after so many years he is an expert, he knows what he is doing and can do it alone. He also knows that if he stays within a certain bandwith, no one has got anything against him. PR over scrutiny.
1.4 The team doesn't exist.
1.4.1 Mr Armstrong didn't dope and the anomalies are natural anomalies or variations that sometimes seem inexplicable, but do occur in human bodies.
1.4.2 Mr. Armstrong didn't dope and a variety of external factors combined (dehydration, diaharea) explain the anomalies.
1.4.3 = 1.4.1 and 1.4.2 combined Natural and External factors
