This is exactly the kind of wishful thinking - scratching the surface - that consistently failed to convince arb panels in TH case. I am not sure it will work any different in Floyd's case.
If you can not show that the evidence is material "to the comfortable satisfaction" of the arb panel the evidence will be swept away as immaterial. That is, using a whiteout may indeed be an incorrect way of changing markings but if it is to prove that the sample belongs to Floyd and that the chain of custody was fine it will be thrown away as immaterial.
RH, you really just don't see it.
If you run your lab, from the administrative to test execution, in a way that so greatly departs from the ISL/ISO, so much in fact that CAS upholds a recent dismissal for in kind departure, how do you expect that the AAA or CAS will flagrantly ignore these egregious violations?
No manual for the machine (ISO VIOLATION). Old, error prone software (ISO/ISL VIOLATION). Failure to secrue the data (ISO/ISL VIOLATION), etc. etc. etc. etc.
It becomes easy to see how they could be doing it wrong, again and again and again, etc. The presumption cannot be that they have done EVERYTHING perfectly, as they have not.
Keep in mind, the whole of the defense is not public. Simply put, you don't know what you don't know. What I do know is that you are now too closed minded, and trying WAY TOO HARD to compare Floyd's case with Tyler's to realize that the Lab BOMBED the testing. Perhaps they will use the "we were overworked/understaffed" excuse like they did in Landaluze?
I think the heart of the issue is that since you are from the scientific world, you are personally invested in seeing the science prevail. Any question of the science, the procedure, the errors is being taken as a shot at YOU. RH, you did not do the test. Ask yourself this, had YOU produced this lab pack, these results, would you stand up in the hearing, in front of the public, on TV and say to the Arbís that based on your work, as is, Floyd doped? If you answer yes, then I think many here will be done with, as will be I. If you are taking this personally, then so be it, that is your problem. I have bigger fish to fry.
