Then he plotted riders performances in the Giro this year over time and it generally showed most of the climbers performed better than pVAM in first week of Giro and then drifted towards or below the pVAM he'd calculated later in the race. The actual winners VAMs all seem to be bob-on what is predicted using 2008-2012 rides as the model's start point. and riders getting slower on fimnal climbs vs pVAM as the Giro went on which is what you'd expect, except for Nibbles and Uran who are able to smash it on the last climb stg. 20 when everyone else was dying.

Is there any chance of getting your data? I’m a political science PhD student, and whilst my research obviously has nothing to do with cycling I spend a lot of time running regressions and I’d like to explore your data a bit further. In short what I want to do is see whether there are any ‘climb specific’ effects that you aren’t taking into account which might be biasing your results. I’m thinking of things like the number of hairpins and altitude, which because they’re the same for each climb are easy to take into account using fixed effects or a mixed-effect multi-level modelling approach. Please get in touch, you can find me on Twitter @CycloChris

2008 represents the last change to the testing/enforcement regime thus
the limits to doping were the same for the whole 5 years (sans UCI
foolery). This means results in this period should in theory be closer
together than if you were to go all the way back to say 2002. Doping
isn’t in the model, it’s good because we can measure it in the residual,
but if there is too much doping variability the overall accuracy would
be compromised.

From the article: Specifically, it is expected that with the introduction of the
biopassport in 2008, this time period will be a more realistic baseline
that is not as skewed by the effects of doping.
There’s no way recent results aren’t doped.  No way.  You need to go back to about Lemond/Hinault era for no blood doping.  Even then, I don’t know what transfusions were/were not happening.  We do know that Grand Tour winners consistently rode and contested a wide variety of races all year long.Which is good enough for me.

Fail.  See Ashenden’s feud with the UCI.  The UCI had clearly positive samples from Armstrong’s “comeback” that did not get routed out of the APMU while riders with similar clearly positive results were routed and sanctioned.
