Hi Bronstein,
IIRC, I was one of the biggest contributors to the Another thing about McQuaid and Verbruggen threads.
I would LOVE to have any OBVIOUS examples of corruption.
But, that is an overstatement on your part, no? (This is not focusing on you, the poster, but on the statement in your post).
I wish it were not.
However, is it possible to do a bit more research before condemning me?
Neither of us, obviously, has access to the "ABP Operating Guidelines" and/or any "provision(s) for such a scenario".
But, we both have access to Google. And, we can both look for any research in this area.
Turns out that there has been a reasonable amount. And, that research would apparently explain why someone like Zorzoli might eliminate sample results that were obtained following extensive periods of training at altitude. Anecdotally, this is
intuitively obvious (emphasis intended) and makes good practical sense - which is why I felt confident making the statements above - even if, unfortunately, it could also provide a back door for cheaters like Rabo, Rasmussen and Leinders.
Having consulted Google, ("athlete biopassport altitude effect") here are some research papers on the topic:
Bonne et al.
Altitude training causes haematological fluctuations with relevance for the Athlete Biological Passport. 2014.
http://onlinelibrary.wiley.com/doi/10.1002/dta.1757/abstract
After altitude training, six swimmers exceeded the 99% ABP thresholds: two swimmers exceeded the OFF score thresholds at day +7; one swimmer exceeded the OFF score threshold at day +28; one swimmer exceeded the threshold for RET% at day +14; and one swimmer surpassed the ABPS threshold at day +14. In the control group, no values exceeded the individual ABP reference range. In conclusion, LHTH induces haematological changes in Olympic-level elite athletes which can exceed the individually generated references in the ABP. Training at altitude should be considered a confounding factor for ABP interpretation for up to four weeks after altitude exposure
Schumacher et al.
High altitude, prolonged exercise, and the athlete biological passport. 2014.
http://www.ncbi.nlm.nih.gov/pubmed/25252093
"...three results from three samples of three different athletes were beyond the individual limits at 99%, one at 99.9% ..."
Sanchis-Gomar et al.
Altitude exposure in sports: the Athlete Biological Passport standpoint. 2013.

"...The Athlete Biological Passport (ABP) is principally founded on monitoring an athlete’s biological variables over time, to identify abnormal biases on a longitudinal basis. Several factors are known to influence the results of these markers. However, the manner in which the altitude factor is taken into account still needs to be standardized. Causal relationships between haematological variables should be correctly integrated into ABP software. In particular, modifications of haematological parameters during and after exposure to different altitudes/hypoxic protocols need to be properly included within detection models ..."
Saugy et al.
Monitoring of biological markers indicative of doping: the athlete biological passport. 2014
http://inado.org/uploads/3/1/2/9/3129436/monitoring_of_biological_markers_indicative_of_doping_-_the_athlete_biological_passport.pdf
The athlete biological passport (ABP) was recently implemented in anti-doping work and is based on the individual and longitudinal monitoring of haematological or urine markers
...
Among the key prerequisites for the implementation of the ABP is its prospect to resist to the legal and scientific challenges. The ABP should be implemented in the most transparent way and with the necessary independence between planning, interpretation and result management of the passport
...
Regarding the blood collection, beside the technical aspects of the blood draw (which must be performed after allowing a timeout period in a sitting position), the timing of the sample collection, the exercise and the exposure of the athlete to altitude (real or simulated) are regarded as very important for the stability of haematological markers. Then, the main points to be confirmed are the following:
▸ No training or competition before the last 2 h of the blood test.
▸ Did the athlete train, compete or reside at an altitude greater than 1000 m within the previous 2 weeks?
▸ Did the athlete use any form of altitude simulation (hypoxic tent, mask, etc) during the previous 2 weeks?
...
Finally, from WADA's website, authored by non other than Ashenden:
Gore et al (including Ashenden).
The effect of training, altitude exposure and an athlete’s sex on expression of genes known to change following autologous blood transfusion. 2012
"...We also showed that altitude training affected expression levels of some of the markers to the same extent as transfusion..."
It now does appear, in fact, that these studies have helped refine expectations in ABP profiles such that altitude impacts/effects can be filtered by DISCARDING the results or by NOT COLLECTING the sample in the first place (emphasis intended).
BUT, that would be quite a number of years since the Rasmussen example that you believe to be the 'obvious example of corruption' that you are proposing.
However, the only corruption here appears to be one of logic and a lack of rigor in supporting ones assertions.
Dave.
