Basing the downvote karma cap on fraction of alltime high seems slightly wrong. There is too much history in that number. Five years from now, that number will have five more years of increasing, making it that much harder for smart new members to break the barrier. Better might be to base it on some function of votes. Maybe a fraction of the number of votes cast over the last n-months. I assume people here generally wouldn't hack the algorithm to get a downvote arrow. If they do, it might be best to make it a function of not just the recent voting volume, but the average of the voter as well as the recency of the parent. At that point, the right cap might be +inf.
