I would prefer not to buy the book but am curious as to the logic. For example, eric lindros had 97pts at age 21 in 93-94, This is adjusted down to 89 in your data. Bobby Hull won the the scoring championship with 81 pts at age 21 in 59-60. By any measure this should be more significant. What does Hull's 59-60 stats adjust to? also interestingly enough, Bobby Hull shows up on your list his last 2 NHL seasons but doesn't show up in his prime years when he was winning scoring championships. Not to be critical as I know you are pulling this data from a database but most of the high stats are drom recent history which makes me wonder about the methodology.
