Correct.
Sorry about the mistake.
Never assume USATF will do what's logical and follow WA's lead.
Regard this "q" issue, with Valby in heat 1, she very well could take off and run close to 15-flat and pull others along to unexpectedly fast times which the 2nd heat cannot match.
Valby is such a confounding factor here that the traditional wisdom of latter heats having an advantage may not apply.
