I suppose the ancient Egyptians were sure that the number of lunar months in 9125 days (25 years x 365 days per year) is greater than 308.5 and less than 309.5, but I am not suggesting that they knew how precise the number 309 is to reality.

The ancient mind may, however, have assumed that the number 309 is exact, but there is no reason it should be a round number, so the search for a very close number fit does not seem reasonable to me.
