Another amusing and obvious similarity are the fans with no obvious credentials or inside knowledge about specific elite doping, or the individual histories of each athlete, taking the liberty of deciding for themselves, based on their gut, which "facts" can be true, and which "unknowns" it is safe to assume.
This also looks like mental gymnastics. Your long rationalization looks like the real goal is for you to justify that your assumptions are safe assumptions.
I'm wondering honestly, what is a possible alternative for an athlete who confesses? When asked "when did you start", the athlete must necessarily answer in the form of "I started then". As to the second part "only did it in between" -- maybe I've missed all of them, but that doesn't strike me as something athletes generally say. I can only recall one athlete saying something along those lines.
This alleged "high school ban" is certainly something that needs a better explanation from the conspiracy theorist fans. Recall 1992 pre-dates WADA, and USADA, and well-defined "whereabouts" rules and athlete obligations, by nearly a decade, and that Jones was still in high school, so hardly considered a "seasoned pro" who should know better. Apparently, she successfully argued that the letter notifying her of the random drug test she missed was misplaced in her coach's office. This was sufficient to overturn the ban, but this whole event is not relevant to the question of whether she doped in 1992. Regardless of your stance on the credibility of the mis-communicated notification, a missed test is not a finding that she doped.
Side note: in 1992, in the USA, a missed test could result in a 4-year ban? I see why WADA was necessary to add consistent punishments globally.
