As is a hematicret rit. Hematicrit doesn't vary by more than a few %. Suddenly yours goes five or six%. For the biological passport. That was effectively meaningless. The biological passport gave it meaning. And that meaning was potential doping,. which meant that you could no longer have it vary by that much, you know
