In lieu of any other data on the cities I'm going to leave them as is, on the basis that: they affect quest XP, there is no other reasonable data for them, and they were later nerfed by Verant after PoP.
I tweaked Kerra, Runnyeye and QCat ZEMs up by 1 because I made a rounding error. QCat is cited at 96 in the newsgroups so it makes sense.
Given all the posts and sources quoted above, this is much closer to how ZEMs were in classic than I suspect the current P99 ZEMs are, and I would encourage staff to quietly make a change if they agree.
