Did the ancient egyptians record the period of the eclipsing binary Algol - the Raging one?

"Normalization allowed us to imitate the pattern of lucky and unlucky days, although we did not know the rules that were used to choose them. It gave us the Q⋆estimates and eliminated some of the unreal periods. The best idea of all was to test what happens after removing . This resulted in the 2.d850 period being the only significant real period and its significance increased. CC does not give explicit clues as to why AES assigned the prognoses with such regularity, but the  period differs by  from the current orbital period   of Algol. If this is indeed the reason for finding this periodicity in CC, then  should have increased about  since 1224 B.C."
