This is a good insight into Paula Radcliffe's blood values. Ross Tucker has written a good explanation about how releasing her OFF scores does nothing more than muddy the waters. They need to be put in context with longitudinal analysis of Hb, ret% and OFF scores.
On off-scores and doping, since you've probably seen that Paula Radcliffe has released the three off-scores in question to the media. Here's a quick summary of what it means (and doesn't): Off-score is calculated using Hemoglobin & reticulocytes (immature red cells). Specifically, the equation is: Off-score = Hb (g/L) - (60 x sqrt(Retic %)) If Hb is high & Ret% is low, then off-score is high, and vice-versa. At some point, the off-score gets so high, it is strongly indicative of doping (the 1 in 100, 1 in 1000 thing). For example, Shobhukova had an off-score of 153 (yikes). The off-score can also be so low that it suggests doping, and these "cut-offs" or limits are known.
