If so, why you also argue based in her performances and other runner´s perfromances to conclude that she is clean? Or, may be you are allow to use the same kind of arguments to base your point that i don´t?
I´m not able to decide the limits of the human ability. You are right, but this is not the limits of the human ability, that´s the limits of that one particular limited runner, that i know very well what are their limits in all runs except that one.
Junxia performance is accept as a good one according IAAF rules. But you see, sometimes we do lots of mistakes, as that journalist did in 1912 about the mile record.
If all the people thinks as you think and no one thinks as i think about Junxia, the drug tests would never been a procedure, Why to use that if the human limits of the human ability, we can decide that? And with so, today we would have 9.6 in 100m by Ben Johnson, Marion Jones would be the olympic winner for 100m, 200m and high jump, the steeple record would be not 7:53 but 7:45 by a marroco runner, and Mohamed Mourith would be still winning cross runs, and Cathal Lombard would be done 27:00 in the 10000m, and the master Edy would keep winning road runs in America. If actually that doesn´t exists that´s because some years ago, a few ones like me we didn´t believed in some performances, and the some substances were considered illegal and they start doing drug tests. If people thinked like you. there haven´t been drug tests - why so if we may beleive in all perfrromances, after all, the human limits we can´t decide...you said.
