They will find that Landis was framed!
Afer reading the research I think that Landis was simply a natural occurence
and that the French lab finding of exogenous testosterone was a piece of bad
testing.
Overall, Tom, I'm not at all sure I agree with you, but here's some
info on your side of the argument.
In some ways, Landis's case can be seen a similar to Mary Decker
Slaney's testosterone doping case (from 1996). This is summarized here.

I recall reading Berry's paper on this issue in Chance (a refereed
journal of the American Statistical Association, although their least
technical one). This discusses several aspects of testing.

The last section, where Berry summarizes, is relevant here:
"Conclusions about the likelihood of testosterone doping require
consideration of 3 components: specificity and sentivity of the testing
procedure, and the prior probability of use. As regards the T/E ratio,
anti-doping officials consider only specificity... Bayes rule shows
that it is impossible to draw conclusions about guilt on the basis of
specificity alone."
There are counterarguments that can be made about Berry's position, but
my lunch break is about over now 😉
