To some degree, Floyd Landis's defense seems to be grasping at straws and playing pr games. Given that they allowed the same lab to test the B sample. They may have already lost the opportunity to prove Landis innocent if, in fact, that is the case.
At this point I don't think we'll have a clear picture any time soon but I do know that Landis's career can be stopped without that clear picture ever being provided.
I wish they had entered this struggle with a stronger understanding of how to address technical and scientific questions both in a public forum and in a legal battle.
On the other hand, not addressing such issues may also indicate that they know that no matter where they go, the test results will be the same.
I'm sure it will all become clear in 10 or 15 years when some insider publishes his expose after retiring.
