The land register recorded that certain water rights were formerly owned by Nysu-Bastet's mother Tewhunet in Year 19 of a king Psusennes. This ruler was generally assumed by Egyptologists to be Psusennes I rather than Psusennes II since the latter's reign was believed to have lasted only 14–15 years. Based on the land register evidence, Wayheset ordered that these watering rights should now be granted to Nysu-Bastet himself. However, if the oracle dated to Year 19 of Psusennes I as many scholars traditionally assumed, Nysu-Bastet would have been separated from his mother by a total of 80 years from this date into Year 5 of Shoshenq I—a figure which is highly unlikely since Nysu-Bastet would not have waited until extreme old age to uphold his mother's watering rights. This implies that the aforementioned king Psusennes here must be identified with Psusennes II instead—Shoshenq I's immediate predecessor and, more significantly, that Psusennes II enjoyed a minimum reign of 19 years. The term "mother" in ancient Egypt could also be an allusion to an ancestress, the matriarch of a lineage whereby Nysu-Bastet may have been petitioning for his hereditary water rights that belonged to his grandmother, whose family name was Tewhunet. However, this argument does not account for the use of Pharaoh as a title in the Dakhla stela—a literary device which first occurs late during the reign of Siamun, an Egyptian king who ruled between 45 and 64 years after Year 19 of Psusennes I. The most significant component of the Great Dakhla stela is its palaeography: the use of the title Pharaoh Psusennes. A scholar named Helen Jacquet-Gordon believed in the 1970s that the large Dakhla stela belonged to Shoshenq III's reign due to its use of the title 'Pharaoh' directly with the ruling king's birth name—i.e., "Pharaoh Shoshenq"—which was an important palaeographical development in Egyptian history. Throughout the Old, Middle and New Kingdoms of Ancient Egypt, the word pharaoh was never employed as a title such as Mr. and Mrs. or attached to a king's nomen such as Pharaoh Ramesses or Pharaoh Amenhotep; instead, the word 'pr-`3' or pharaoh was used as a noun to refer to the activities of the king (i.e., it was "Pharaoh" who ordered the creation of a temple or statue, or the digging of a well, etc.). Rolf Krauss aptly observes that the earliest attested use of the word pharaoh as a title is
