i think it bears repeating that only riders with a 0 or 1 are considered to have a clean blood profile.
from 2 up, they are suspicious.
the spectrum from 2-10 of how suspicious they are may depend on a lot of invariables -- when were they tested, how many times were they tested, did they benefit from long showers, paid off UCI testers, advanced knowledge of testing and exclusive contracts with a doctor that has decades of experience in blood and can "stabilize" their parameters in a few minutes...
to me there really is little difference between a 2 and a 10.
