There may be some confusion when looking at the two sets of averages in posts #19 and #20.
The first one was derived by adding all the averages in each age group, and dividing by the number of players in that age group.
The second one was derived by adding all the points scored by that age group, and dividing by the number of games played by that age group.
As a reference point, the second one in post #20 is probably the better one to use.
