This keeps coming up, but here it is again. The emphasis is now on WORLD RANKING. World Athletics doesn't want to post a time standard and take in anyone and their dog who hits it. So they made the time standards really hard, such that a lot of the field will be pulled in through the world rankings. And for the most part if you are someone who can hit the world standard, you more than likely have the world standard.
So really people should just stop looking at the world/olympic standards. The world ranking is generally how you qualify now. The world athletics site has a nice filter where you limit to 'top 3 per country' so you can see what type of world ranking score is good enough to qualify. Then you filter by country rankings, and anyone who has a ranking score higher than what you saw as 'the last guy in' at the world level can technically qualify.
Here is an example, let's say they will accept 24 athletes for the 10,000m on the track. Limiting to 3 per country, Jack Rayner of Australia is the 24th highest ranking score athlete with 1186 points. For reference Sean McGorty is the USA #3 guy at 1207 points. Right now USA only has 3 guys above the 1186 points that is the 24th spot right now, Grant Fisher, Joe Klecker, and Sean McGorty. Those three would go to the olympics right now since we have exactly three, even though only one of them has the 'standard' of sub 27. The standard doesn't really matter, it's about the world rankings now. Let's say Mantz runs a little better and moves up from a 1177 score to a 1190. Now USA has 4 guys who have a ranking score high enough to be in the top 24 when limiting to 3 per country. Now you have a race amongst those 4 guys at the US championships to pick the three guys we send. And it is possible that there is a 5th guy, who is right on the outside of being ranked high enough and if he could win and get the bonus points for winning USAs and have a fast 'enough' time such that it improves his ranking score above that 1186 then that person could now go.
So the standards don't really matter, it's largely about world ranking now. And bonus points are a large part of the ranking, so if you can run fast and WIN a big race, you're going to be rewarded with a good ranking.
