How exactly does the “All-Time Top Performers, Men’s LCM 50 Butterfly” list not include the world record?

Need to add in Van’s 22.87 time trial – would have been second tonight.

Looks like he moves up to 4th all time in US history (not counting Ilya until he’s officially repping America)

An American going 22.6 in the 50 fly šŸ™

Is 22.7 22 mid or 22 high?

high

22.0 is 22 flat, 22.1-22.3 is low, 22.4-22.6 is mid, 22.7-22.9 is high

This is the exact range I used when discussing early/mid/late 20s/30s/40s etc with my friends and they were mad at me.

Is that supposed to be an American men all time 50 fly list? I think Santos snuck in with not his best time?

Really hoping to see Kharun lower that PB at Nationals and inch closer to that Dressel record.
