The Tribunal noted that the IAAF had established that both of Slaney's specimens had been analyzed as having T/E ratios significantly higher than 6:1. The tribunal also observed that Slaney's longitudinal study revealed a previous T/E ratio high of 3:1; meaning that her present ratio, by the most modest of calculations, was more than three times greater than she had ever previously tested.
A 3:1 ratio is an indication that someone had been manipulating her T:E ratio to be within the allowable but 3 times the normal ratio (1:1).
It's significant that Alberto had been sending his urine to Victor Conte in the 80s, but for what? Conte wasn't a doctor, nor was he a scientist. He was a drug dealer.
It's also notable that Marion Jones, like Alberto, also a BALCO client, was sending her urine/blood samples to Conte to be evaluated at Quest Diagnostics for T:E ratios. There is no known medical purpose for T:E ratio testing. There is a known purpose for testing T:E ratios if you are a dpoer planning on compteting in track and field.
