Yeah. I had Fable run through every version of it I could think of and it explained the numbering system was the root of everything being divisible by 60.

I did find a pattern though. If you look at ALL the kings, rather than just those 8 it becomes obvious. The recent numbers are realistic and drift further apart, becoming less and less accurate, the further back you go.

Interestingly it also compared some other clay tablets and they were close. So it seems that they were probably written down based on a verbal history that had already drifted wildly well before it was written down .
