Publicus said:I'll play along as soon as someone shows me the sampling error, especially for the region where the beef was raised/slaughtered--and I'm almost certain it is higher than you expect (small sample sizes produce large sampling errors).
Listen, I'm not defending Alberto or his argument any further than to say it remains plausible, however unlikely folks may contend that it is.
Publicus said:Don't disagree. Just pointing out that it is never, ever, ever, ever zero. And so far as I know, no one has provided the sampling error. So it's difficult to assess how accurate the very small ratio actually is, especially when you drill down into the unique data sets.

joe_papp said:There is fanaticism afoot and the assumption that there is all-pervasive corruption at an organizational level at not just the UCI now, but the Spanish federation, is becoming to sound unbalanced and paranoid.
Merckx index said:OTOH, as a scientist, I have never, ever, ever, ever heard of a 1/20,000 overall chance (based on a sample size of millions) that, as a result of sampling error was "really" less than one in a hundred. If you would like to provide an example, I'm all ears.
Cobblestones said:Wrong.
Apparently there's places where clen is used to such a degree that people get clenbuterol poisoning. That means you might ingest a pretty hefty dose by accident. So, if you want to set a threshold which eliminates positives from all accidental contamination from food, you'd have to set it so high that any testing would be meaningless. Hence, you have to put it at some arbitrary lower value. But then you'll still get cases of accidental contamination. So you haven't really gained anything. Better leave it where it is. If accidental contamination can be shown then it can be shown. It really doesn't matter what level it leads to as long as it's accidental.
Publicus said:Thanks for clarifying Lanark. If I was Li, then I would be more than a little upset. Did he appeal his ban to CAS?
I too would like to know the derivation of the 1/20000 statistic. I have read the EU reports on residue testing and the results even in recent times seem to fluctuate from year to year and definitely geographically. Going by some data in some years you might infer almost no chance of a contamination while in others it could be 1/2000 or less. Furthermore, that is across the whole EU while most positives occur in one or two countries so if you are eating meat from those countries probability is going to be greater. Unfortunately EU testing data is not full broken down by country although the data on positives is.131313 said:I'm still all ears (or eyes) to see, in print, the origin of the 1 in 20,000 chance of testing positive" claim; something besides "I read somewhere" and "some guy said".
Publicus said:Do you understand that a 1 in 20,000 chance is a meaningful number when the population of cattle slaughtered in the EU is somewhere around 28,000,000? Not to mention the millions of carcasses that are imported from Brazil and elsewhere? Not to mention, once you start dealing with statistical sampling, there is this thing called a sampling error that must be account for in your analysis.
Simply declaring his defense as implausible because, well you declared it, doesn't carry any more weight than someone saying he didn't do because he didn't. That may work in the school yard (and the clinic), but that won't get you pass elementary logic in most high schools.
Ryaguas said:So when I read this I just can understand that you rly think that Cycling was cleaner before Contador positive right?
Altitude said:Isn't that the point of drug testing? To catch and ban athletes with banned substances in their system?
Altitude said:"Somebody spiked my water bottle. I can't prove it but it's the truth."
"A road side spectator jammed a syringe in my *** when I rode by. I didn't inject that EPO."
Altitude said:Anybody can make up a BS story about how something got into their system. Unless they can prove it, they should be sanctioned.
correct.minessa said:Li can not prove that he has not used clenbuterol in high doses. Here would help a hair test, but Li did not have the support (such as Ovtcharov) of the best German anti-doping experts.
There are plenty of valid arguments regarding the implausibility of AC's food contamination defence but the one you use here is irrelevant. The levels of clenbuterol required to produce the symptoms of poisoning are orders of magnitude higher than ACs levels.Paco_P said:Anyone claiming the plausibility of Contador's defense has to consider the following: there is not (otherwise) a documented case of clenbuterol poisoning from ingestion of beef in Spain in recent years. The parsimonious hypothesis, because he is a cyclist, is that Contador got the clenbuterol from doping.
Porphyry said:Very glad to see Contador cleared. It's not right to sanction an athlete for testing positive for a minute amount of a banned substance that can be picked up inadvertantly through food and could not have had performance-enhancing effects.

Maybe you should actually read the headline. He criticises Spain, not the RFEC. And he clearly does:Aguirre said:Cyclingnews.com continues poisoning the public opinion when releases this headline: McQuaid criticises Spain after Contador decision
well, I have read what Pat says and I don't see any critic to RFEC, his reaction is measured and based in "we have to study the papers, he is allowed to race, etc".
The same poison was applied last night when using the spanish flag as a patriotic affaire.
Why wouldn't they have sent the full documentation from the get go? I assume that includes the appendices, including the scientific reports we're all dying to see - the ones that rule out a blood transfusion."We got 35 pages from the Spanish Federation yesterday, which has to be translated and studied, and then we'll discuss it with WADA. We'll wait for the full documentation from the Spanish Federation and then we've got 30 days to decide whether we appeal or not. It's a UCI decision."
