Because you could test for it in a kid who is far from physically mature and get a sense of their raw ability.
I believe the rest of your post is what you would call hearsay.
Got a test that "proved" something and doesn't remember the number?
The dude would have a T shirt with the number on it and some slogan mentioning why it was BS.
It's "hearsay" when I heard it from THE GUY HIMSELF?!!!
Now you're grasping at straws. When VO2 max can increase by 50% on 5 months of nothing-special bike training in high responders, it shows you how worthless baseline VO2 max is. And when it varies so much between elite runners, it shows you how worthless it is in predicting current performance. You already have all the info you could ever want in training and PRs.
That's why Jack Daniels had to come up with a second variable, "running economy," which is basically "your running speed divided by your VO2," in other words, "difference between how good you are and how good your VO2 max is." And yet there's never been a good explanation for what causes people to have a good or bad running economy. Supposedly it has to do with running form, yet Salazar scored quite high and Rupp scored quite low so that doesn't do much.
"The dude" has no reason to brag about his low VO2 and no reason to remember it. That would be a desperate move for someone who is actually accomplished in the sport, even if he wasn't humble. Besides, the vast majority of coaches don't care about VO2max in the first place either, it's not like he's in some minority. He and most people recognized the worthlessness of VO2max way back then, why would he even give it a second thought now?
