Then you are quite wrong as I understand all of those things.
I agree with you that the greasy half-eaten pork stomach burrito is the only candidate to be evaluated. As unlikely as it is, it is still the most likely candidate as it is the only one with any evidence before the CAS. I am not throwing up any other alternative than the one presented to the CAS. The AIU didn't evaluate her burrito specifically, but counted all the pigs in the USA, and still the AIU expert effectively opined that up to 12,100 pigs per year could cause nandrolone positives, and that during the pandemic, the AIU pig expert conceeded many pigs ate soy due to the unavailability of corn. Ross asked why look at pigs in Europe, but the AIU experts (from Texas and Canada) looked at pigs across the USA and in Canada -- why not look at pigs locally in Oregon, adjusting the statistics for factors during the pandemic?
I also agree with you that it is also not Prof. Ayotte's job to suggest nandrolone products available on Amazon, as she is not Houlihan or hired by Houlihan. But she did. Like you said, Houlihan did not argue these things, and Ayotte is just throwing up a shot in the dark. Many letsrun posters are doing the same.
Here at letsrun, we are in the real world. While I don't disagree with "alternate universe", in discussion forums, real world standards apply. Posters here go far beyond what was established by Houlihan, the AIU, or the CAS, with baseless judgements of Houlihan, Jerry, Shalane, the BTC, and suggestions that Houlihan's progress and AR performances were not clean. If posters here are not limited by the roles and definitions defined by WADA, and the evidence before and findings in the CAS report, why should I be?
If you, or others, want to convince me that intentional exogenous nandrolone is more likely than a pork burrito, that would be your claim (or theirs), a "shot in the dark" not supported by any AIU or CAS evidence, and your (or their) burden to support. That is where we are now -- a bunch of baseless claims extending far beyond the CAS ruling made within an artificial framework defined by WADA to make prosecuting ADRVs easier, at the expense of athletes.
I also understand that Shelby was solely responsible for proving "not intentional" and ultimately having to determine the nature of ingredients in a burrito she ate one month earlier. This seems to me like an impossible burden and the system that places that burden on her is not a just system. I agree with the longtime USADA chief Travis Tygart that this version of justice railroads innocent athletes into 4-year bans and risks treating innocent athletes like dopers. Does this include Houlihan? There is simply no way to tell from the CAS report and the current WADA adjudication process.
I have lost hope that most here would even attempt to understand, as they are now blinded by my handle, but I hope you read the contents of my posts and understand.
