Here is a graph of the reaction times from the semifinals and finals of the 2003 - 2022 World Championships.
Men - 100m and 110h. Women - 100m
(Not including the women's 100h because it hasn't been run yet.)
As you can see in the graph in this link, the reaction times in Eugene are significantly lower than any other World Championship in the last 20 years.
Something is wrong with Eugene's starting blocks and the reaction time software that they are using. It's calculating reaction times incorrectly, taking about .02 seconds off of the average reaction times from previous world championships for the men, and taking off about .01 for the women.
This problem explains the four runners who were DQ'd for supposedly having reaction times of .09x, even though in reality their reaction times were well over the allowable .100 , potentially costing those runners medals and prize money.
C'mon Eugene, get your act together!
