"re: Years 63 to 94 not being attested - how many records are there of dates in years 1 to 62?. If there are only a few then the last 30 years could just be non attested."

Well, if you really want to know, my study led me to conclude that these later 30 years belong to the Early half of Dynasty 7 which should be regarded the end part of Dynasty 6, which includes Pepi II's son and successors down to and including king Neferkare Khendu. In short: Pepi II reigned for 64 years from 2396 to 2332 BC as the actual end of Dynasty 6 since 2500 BC, forming a period of 168 years. Then follows his son and Neterkare Siptah and Menkare (combined the supposed "Netequerty") and others considered part of Early Dynasty 7, for a total of 30 years until and including king Khendu, who ends his short reign in 2302 BC, thus closing the Old Kingdom. From then on we are left with Dynasty 7 proper, followed by 8, 9 and 10, contemporary with Dynasty 11 until Year 35 of Mentuhotep II (2068 BC), followed by Mentuhotep III and Mentuhotep IV and his Vizier Amenemhat, who eventually became the first king of Dynasty 12 in 2020 BC precise, and this Dynasty lasted until 1825 BC when the power went peacefully to kings of Dynasty 13. Eventually Dynasty 15 ended by force in 1562 BC and power went to Ahmose of Dynasty 18, who began his reign in 1578 BC. This precise scenario can be fully accounted for. So no. The 30 years after Year 64 of Pepi II did not belong to Pepi II but to the remainder of Dynasty 6 = Early Dynasty 7, and that is why Manetho counted 197/8 years for Dynasty 6, which is certainly 30 years in excess.

This forum is awful. I can't even edit my posts properly, so I give up.
