P.s It also looks as though the raw data Dopeology uses for its figures is unreliable. For example, the totals by nation are aggregates of the figures for individuals. However, even the briefest consideration shows that the 'incidents per person' these totals are based on are widely inaccurate and inconsistent.
For example, Ullrich is listed as having 12 incidents against his name, which also includes such things as appeals. With Gaumont, each admission of using a specific substance is recorded as being a separate incident, and so forth. However, Armstrong is listed as only having 9 incidents against his name, with whole rafts of incidents being gathered together into one count, as with the USADA investigation leading to his permanent ban.
'Garbage in, garbage out' as they say.
