The whole thing is clear as mud - thank you USATF.
Look if the trials were in Houston at 7:00 AM then the results would produce fast times and all of this would take care of itself by the end of May. BUT the issue is that IAAF qualifying system doesn't really match with running in Orlando from 10:10 AM to 1:00 PM. It could create all kinds of crazy results with the weather. That's a fact, just like every Olympics, World Championships, European Champs, Commonwealth Games, etc. and the LA Trials in 2016, Pittsburgh 2000, etc. that were run in warm and humid conditions. It impacts people differently regardless of their lifetime PR's. This is not a PR course like Chicago, Berlin, Rotterdam, Seville, Valencia, etc.
If they would have just left the Olympic standards the the same as 2020 then all of this would be a moot point. That seemed to work pretty good producing about 100 runners for both the men's and women's fields. Compared to 2016 when there were about 155 in each.
I'd be looking to see who has placed well in hot weather races. Recently Lindsay Flanagan and Zach Panning both ran well in hot and humid conditions at the Budapest World Championships. Those are the kind of people we need on the team who can compete well in Paris on a challenging course in August weather.
