I'm somewhat confused with the way the WC and OG qualifying standards work. Even if you make the A qualifying time, you still dont make it on your country's team if you didnt place 1-3 at your nationals? cause I'm seeing some 100 meter sprinters running fast times, for example Coby Miller, who got 4th in our Nationals, but it still doesnt matter cause he didn't get 1-3? If someone can clarify for me it would be greatly apprectiated. And by the way what is the qualifying standard for the 100, like 10.15 or something like that?
