considering that there were probably close to a dozen Eastern bloc dopers running times close to or better than Muir and even not far from Didoper and the Chinese EPOers throughout Decker's heyday in the 1980s, and that she beat them all for double gold at the World Track and Field Champs in 1983, and ran 1:56.9/3:57 over 30 years ago (and notably over a decade before the Salazar testosterone test), that's far and away beyond this current Scot, who in my view is dubious at best (runs in the 40s per week, we hear now--ludicrous).
