EA Ermor healing and healing mechanics

[rabelais]

I have 39 afflicted units in my capital, with 92 total afflictions among them. 9 bishops (20) and an arch bishop(30) all healing. Healed for 4 turns.


turn 1 = 2 individual afflictions healed (no units totally healed)
turn 2= 4 afflictions healed (1 unit healed)
turn 3= 5 afflictions healed (no units)
turn 4= 1 affliction healed. (no units)

Now I know ermors healers are inferior to arco, and its true that some of the units were old or diseased, but surely the math here is a little nonlinear?

Can someone explain why the cure rate is so low relative to the expected value?

Also is there a spoiler on age and scales/paths? I can't find one via forum search and the manual is not helpful.


Thanks for your time,
