For age analysis, you always get a small number of players who impact early in their careers, and also a similar number of players who can impact late into their careers.
However, for most players this means a 50 game improvement ramp up, and a 50 game drop off either side of their 'peak'.
If you want to apply statistics sure.
And we can, we can say that Byrnes probably needs his 50 etc.
But we know the ACTUAL players on the list and there aren't so many that we can't talk about them individually.
