Ask PG: do you cap karma averages?

4 pointsanigbrowl3 comments

Lately I've noticed that while my karma continues to rise, the average-karma-per-comment remains locked in place. Over several weeks, neither highly scored (> (total/average)/100) nor multiple single-point submissions cause it to waver. Is it only recalculated periodically, or is there some external constraint?

PS not that I mind if you do, since I'm not the HN target demographic; just curious.

pg: "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."

Also, pg posted the code to calculate karma/comment average. It doesn't include the karma of your last 5 posts or your highest ranked comment: http://news.ycombinator.com/item?id=1853688

Good catch. Given the increase in readership that'd explain things.
