I don't have that much rep on SO (about 3.8k), and I've been less active over the last month or two, but I've noticed that I still get a trickle of rep from the occasional upvote on my old answers (85 over the last month). This momentum is obviously going to be more noticeable to someone with much higher rep given the larger surface area of questions/answers to catch stray upvotes, which got me thinking, there must be a point at which reputation becomes self-sustaining...
Based on my 85 momentum over a month on 3800 means, I'm getting a ~2.2% increase per month. Assuming I'm vaguely representative, to reach per-rep-tual (yes I went there) motion, you'd need about 275k rep (275k * 2.2%/month = 6k/month = 200/day = daily rep cap).
Obviously my extrapolation above is not going to be very accurate (nothing like stats based off one data point), so I was just curious, has anyone done any analysis of the data dumps to see if/when high rep users will reach a point that they will continue to hit the daily rep cap without any further contribution?
(note: I don't see this as a problem, more as a simple curiosity)
