I think even CSI - Thebes is going to have trouble proving the actual motivating logic of the AE.

Personally, with the moon have a 28 day cycle, his wife having a 28 day cycle, I THINK an AE could have accepted a 1/28th quite easily as a natural number for a cycle...

But that's a "fer leap" from saying they divided it into 28ths because of the lunar cycle.

Jammer

PS; After all we KNOW Ted Bundy killed 30 college age girls and younger, we don't still know exactly why, and that was only 30 years ago.
