Just accept reality.
That's a great chart in showing that a change in the 12 month age range can mitigate RAE but it might be the result of just layering SY and BY RAE on top of each other in the cumulative data. He should do a Fischer's transformation based on birth year on the two populations to test this. Considering he thought SY in 2023 was birthdate cutoff for these players who were up to what 40 years old, he didn't even think of it. It's why you do research on the subject you know with data you know.
Ahhh, but the author said nothing about that. Sounds more like your reinterpretation of the data.
Is your position that because the author didn't know that youth soccer went from SY to BY in 2016 that it didn't happen?
No its because thats what the data says.
Your personal views don't matter.
So we should ignore actual rosters, US Soccer and multiple studies from actual academic organizations
But listen to a dude who came up with your madness chart
Or just read and review what the data says.
Which is that American pro players birth month is equally distributed though the year.
Over half of the pro players in America's MLS are foreign, aka didn't play here as kids.
Sorry, that's not the best counter argument. The data takes country of origin (not where they play) and birth month. These are American players.
Not true, go back to the database.
"For the purpose of this research, I collected player data from a Football Manager 2023 Kaggle dataset, a comprehensive source with details on over 150,000 players, including information such as age, weight, height, preferred foot, club team, nationality, and most importantly, their birth date."
