I'd be willing to bet there's someone who can run ~4:20 but can't crack 60 in a 400m. A very rare outlier, yes. But I'd bet it's possible.
Have you found the person? If such a person is listed, said person may have raced last 400m in 8th or 9th grade. By senior year 1600m time down to 4:20. This hypothetical person would be capable of much faster than 60 seconds for 400m at the time said person raced 4:20 for 1600m. Proving me wrong is to show a person racing 400m in 60 seconds, a relay leg is ok, the same school year racing 4:20 1600m.
If this person exists, it likely isnt a senior in high school. It would need to be somebody with an extremely well developed aerobic system, something that takes 8+ years.
I wouldnt be surprised at all if a very few 30 to 40 year old runners can run 4:22 in the mile with a current 400m ability of 60 flat. Outliera may be hard to find, but that doesnt mean they dont exist or arent possible.
The real issue is how are you going to find a FAT 400m time for that person? So you'll just have to believe anecdotes. I had a teammate who was a 29:30 10k runner. He ran 4:15 at the end of a DMR and he never ran faster than 28 for the 200m in practice.
Another teammate if mine was a 30:30 10k runner who ran an all out 400m in practice on multiple occasions, because he was obsessed with how slow he was at it and wanted to get faster at it. He was stoked to run 61 one day. He ran 4:05 in the 1500.
If youll never be satisfied that a 60/4:20/4:22 is possible unless you see FAT times for somebody at the same relative time, then we will probably just have to agree to disagree, since I'm not sure anybody is going to find that evidence for you that meets your burden of proof.
