I THINK Redbird is in error in one or two of the percentage advantages
What I did actually is mix up the names, but basically the numbers counting down from Deity are 0, then 50 for Emperor, then double each one (100, 200, 400, 800).
I'll edit my original post above.
2nd Edit: I'll just list them here again as well [names corrected]:
(Chieftain=800, Warlord=400, Regent=200, Monarch=100, Emperor=50, Diety=0)
