Did exclusively Permafrost on my shaman 55-60 shortly after Velious release, before the ZEM shuffle. I remember being level 59 and getting 1% per 4 bears on an Ogre.
I'm level 55 on enchanter, and getting similar exp now. Have done hours here to get a good average and am averaging about 0.4% per bear. (average 4% per 10 bears over 6 hours)

If the above EXP table is accurate, then the ZEM is below 100 for Permafrost now. Low end bear is level 43.
43^2 = 1849.
1849 * 100 = 189400.
189400 / 33M 500k = 0.6%
With a base ZEM of 100, I should be getting 0.6% per bear. Or 6% after 10 bears.
0.4% of 33M is 134352.
134352 / 1849 = 73.
Based on the evidence I've collected (and corroborated with other people who say Permafrost feels very very slow nowadays), the ZEM from Permafrost went from 150 down to 73? (Maybe 75 and was just cut in half).
I know it's old, but I plugged my experimental numbers into
Green EXP Calculator and got similar results. I plugged in a level 43 mob, with a 72 ZEM, at level 55 -- and it says approx 240 mobs to ding.
That is in line with my experimental data of 4% per 10 mobs.
So the ZEM was cut in half? That seems a little much? Anyone else have other data?
