Interestingly, the author of the 110 point comment has no submissions and only one comment - that one.
Oddly enough, I THINK (I'm not looking it up, and if I'm wrong, let me believe the lie) the first word he dropped in that game was 110 points as well.

Yuck. I hope it's a rolling average (i.e. the average from the last 30 days). My account is 1368 days old! How the heck am I supposed to change my average in any significant way?
The real work here is done by * frontpage-rank* . It's implemented as follows:
(def frontpage-rank (s (o scorefn realscore) (o gravity gravity* ))
(* (/ (let base (- (scorefn s) 1)
(if (> base 0) (expt base .8) base))
(expt (/ (+ (item-age s) timebase* ) 60) gravity))
(if (no (in s!type 'story 'poll)) .5
(blank s!url) nourl-factor*
(lightweight s) (min lightweight-factor*
(contro-factor s))
(contro-factor s))))
The first few lines here won't change too much here for either comment. Obviously, the 110 point comment will have a higher base score than the 17 point comment. They're about the same age, so (expt (/ (+ (item-age s) timebase* ) 60) gravity) will be about the same for each of them. So the division will come up with a number that's a few times higher for brh's comment.
The interesting part is the multiplication here. I don't think either would be considered a story, so neither is being multiplied by .5; neither has a blank url, so they're not getting hit by nourl-factor.
It comes down to the final part, whether one is considered "lightweight", and what the contro-factor* of each is. It takes into account the number of children of the comment (the visible-family call). It shouldn't make a difference, though -- neither of the posts has more than 20 children, so contro-factor for both should be 1. I think I'm missing something, as what I've said wouldn't explain the ordering.
Notably, though, it doesn't take into either account karma or average karma of the poster to determine rank.
Edit: as ChaosMachine pointed out, it does take into account users' average karma: http://news.ycombinator.com/item?id=1923716 . Ey pointed out that pg's post is here: http://news.ycombinator.com/item?id=1398764

I can't find anything in the arc source to support that. Can you point me to something?

Maybe I wasn't as confused as I thought I was.

The average is calculated by taking your most recent 50 comments, dropping the first five, dropping the max, and averaging the rest. Yours is currently 7.14 (it's in your profile), a very high average. For comparison, of the 100 people on the leaderboard, there are only nine with a higher average.

Based on the formula you just gave, my average should be 3.27, but it still shows 2.55.
I realize it's a bit of a meaningless metric, but it's something I've been idly pondering for a few days.

Slightly off topic, but do you have any idea how often the average is recalculated? I only ask because I've noticed that my average hasn't changed since it appeared in the top bar, yet I've doubled my total karma in the last two weeks.

"There's a background process that runs every 45 seconds and picks a random loaded user to update the average of. Empirically, not more than every couple days, at best."
