It sounds like scientists actually revealed how to read a table of predictions in a document:
> Juteson and Lowry reject the long-standing assumption that the table was reset at its final position (that is, that it was intended to be used on a continuous loop, returning to month 1 after reaching month 405).
> The trouble is, using the table in this way doesn't actually work.
> ...Instead, they propose that a new table is begun in the 358th month of the current table. With this approach, the table's predictions are only about 2 hours and 20 minutes early for both Sun and Moon alignment.
