First off I doubt God would work as a last level because it would be confused with gods. Second it shouldn't matter how many post it takes to get to a level, as long as you earn the xp required. I like to answer questions alot causing me to have about an average of +3-7, which would make me a Pilgrim though I have enough xp for a Friar and almost a Hermit (at the time of this writting based on your chart), if my average node rep determined my level I'd proably stop answer SOPW questions, if there are others who would do the same this could ruin the best part (or at least most used part) of PerlMonks. While some people might be able to write a couple of xp getting Meditations, I only have time for that during the summer (when school + work don't take up all my time) and I'm not the best at thinking up good meditations either ;).
