From article: "Hell, consider that Bolt has run a 9.59, a 10% reduction in performance is a 10.51." I am not sure if I understant this correctly(non english speaker here) but do you suggest that he would run 10.51 without drugs?
He run 20.58 over 200m at age 16. Some people have just simply lots and lots and lots of talent.
Usain Bolt will be first with or without drugs.
There is no rule that drugs add 10% to result in every sport, maybe in weighlifting drugs add 10% but in majority of sports no.
