bret knows better, the 60 foot clocks were not fast at Piedmont no more than they are fast at Atco where I had run 1.29 60 foot several times, though you and the rest of team clueless would like to think so. The ET's were fast because the air was good and the track well prepared that day 5 years ago.
Meanwhile, the 60 foot clocks must be fast everywhere I run now because whether I'm running at a near sea level track or one whose elevation is 1000 feet above and whether I'm running in 1000' of air or 4000'+, whether I'm running in NJ, PA, DEL, MD, VA or NC, my time slips show 1 teen 60 foots and 9.0x passes.
