If you obtained the information externally then I have to question your use of "XP per Post"
. There have been a number of Perl Monks Discussion
s over the years about having a way to break down where XP came from (logging in, casting all your votes, voting on a node, having one of your nodes voted on, etc). From my limited knowledge of the topic, there is no way to know how much XP a particular node earned you without keeping meticulous track yourself.
I would only suggest that you change the column heading to "XP / Writeups" as I assume thats what you did.
