Else where in this thread you said:

the longer you've been ABLE to participate is a distinct and obvious advantage

I hard-coded your data for you into the Ranking the Saints by XP Efficiency script since you have not yet been inscribed in The Book.

The data appear not to support your proposition, I am afraid. Quite a number of the Saints are around your age, or younger. (limiting to top 25 + trippledubs)

perl XP_efficiency.pl -r 1 -s age -f trippledubs -o desc -l 25

Now I am no statistician, as I mentioned earlier, but it does seem to me that the number of posts made has something to do with the game.
