A bit alarmingly, 102 hours in the last 2 weeks. I've been conquering the Slavic Union. Slavs are my kryptonite. I've had maybe 8 attempts at reforming them, and it always goes wrong somehow. I run out of CBs, or run out of MA, or whatever. This time there were four occasions when I thought I was within an hour of it, before something came up. When I finally got it I thought I had missed on MA and would have to knuckle down for five holy sites, when suddenly I jumped 20% for no reason I can explain. I reformed without delay...
Maybe I should try to reform the Tengri. That looks hard...

Tengri is the one faith that I haven't been able to reform yet, but I haven't cared much for nomadic gameplay the few times I've tried it, and Bulgaria is so far away from the holy sites. Start as the Mongol Empire in a start date when they're active, though, and it should be relatively easy (the only time I've seen the AI reform the Tengri faith, it was the Mongols that did it).
Slavic usually isn't too hard to reform, depending on which realm you start out in--places like Croatia in 769 would be fairly difficult, but starting in 769 in Poland or Pomerania isn't so bad. You do have to be careful not to over-expand too quickly, though.
Zunism is tough because of the Abbassids, unless they fracture early. Bon is pretty easy if you start in 769 Tibet. African just takes persistence, usually. I used to think Sousmenusko was hard, but in my current game I found a start that made it almost laughably easy. Germanic isn't to hard in 769.
