That's over-simplifying by leaving out the "or more" part (which presumably exists because they only want to count full blocks). I do understand the gist of what they are saying but there's got to be a better way to word it.
I also wonder if theres a good statistical reason for only counting full blocks. Why not just stop at 30k?
Right, but you could use a fraction of the final block (using the known vote percentages for that block). Then it would be "a moving average of the last 30k votes" and not "a moving average of the last 30k or more votes".
