I know this is an OLD topic but I can't help but reply.
Now I may be wrong, and if I am and missed something then cool but...
I always viewed the Dark Ages part of VTMR to span 50 years from the time of Christof's Embrace to when he gets smashed in Vysehrad. 1141 being his Embrace and its 1191 when he goes into Torpor.
Which brings us CLOSER to the "800 supposed years" timeframe he was asleep.
Either that or it was 58 years the Dark Ages section takes place.

Yes it does not seem like that in the game.
Reason why though is because at the end of the game while in the "Wall of Memory" and Anezka is talking about what she has been doing the whole time she mentions that "its been 50 years since Vukodlak took me."
And THEN AFTER that in the next entry she mentions on how "My beloved Christof has perished in the fall of Vysehrad..."
So yes, historically its completely screwed up, but if there is that 50/58 year gap that may explain how it goes from 1141-1999 and it be 800 years of Torpor.
Maybe, maybe not but thats how I always viewed it based on the conversation
