I believe the “karma in last 30 days” is “karma on new contributions in last 30 days,” though I would have to check the posts where its introduction was discussed to make sure.
My karma for the past month in the blob is currently 187, and the sum of all karma for comments since November 16 (inclusive) is 159, so that suggests that I gained 28 karma from old comments this month, or the algorithm is working in some way I haven’t thought of.

Interesting—it should be easy to verify...
