Approximate dates of Christianization?

So most of the sources I've read for this topic give wildly different answers for different reasons. Would anybody happen to know and/or have a reasonable educated guess as to the approximate dates for the point where 50% of the population had been Christianized?

I'm more interested in prior to the 14th century since that's when it gets easy to figure out, as I'm looking to make a reference sheet to concisely list this out for timeline research purposes. The only region I can say with 90% certainty that I have an idea of right now is the Levant.
 
Everything that ever fell under Charlemagne's territory was Christian by 850. Poland was Christian by about 950, Denmark and Hungary by the turn of the millennium. Russia was probably about 1000 as well.

I would just go by the time that a king became Christian, as the commoners will eventually follow the king's lead.

There is too little recorded history in these places to say anything more than a couple of wild guesses.

If we're counting the peasantry, Lithuania stayed mostly pagan (well, sort of) all the way to the Counter-Reformation, as numerous sources like Mikalojus Daukša and Martynas Mažvydas point out.

Except that it wasn't the old paganism, it was a kind of weird syncretism between Lithuanian paganism and Christianity - they would believe in God, but also state that the old pagan gods are his "angels" and representatives in the mortal realm and in order to gain their, and by extension God's favor, you need to provide sacrifices to them, just like in the good old days. I think Virgin Mary was also added into the pantheon, or at least the people really liked to celebrate her in her dates.
