Maybe the Sun King needed 10 helpers for delaying the Queen - one for each day up to and including Tagaroa Uri 26 (299). The synodic cycle of Jupiter is 399 days and if the year was beginning 100 days before January 1, then Tagaroa Uri 26 would be day 399. April 10 is day 100 and day 265 is September 22.

... Honga came and gazed in the direction below (i.e., toward the west). He called out to the noteworthy ruler (? ariki motongi) Hotu: 'There is the canoe of the queen! It will be the first one to land!' At this news King Hotu replied to Honga, 'Recite (rutu) ('powerful incantations') as though the ten brothers of the chief (ariki maahu) were one whole (?).'

The ten recited with all their might. This is what they recited: 'Let all movement (? konekone) cease!' They recited and sailed on swiftly: Honga, Te Kena, Nuku Kehu, Nga Vavai, Oti, Tive (corrected for 'Sive'), Ngehu, Hatu, Tuki, and Pu (corrected for 'Bu').

He worked mana in the fishing grounds. (Naming of two fishing grounds.) ...

The pair of 'fishing grounds' where mana had to be worked could have corresponded to 5 days each:

Possibly Pu alluded to the month Tehetu'upú ('February').

 ... the first month of the Moriori year, was named Rongo (Lono). On the first of the new year the Moriori launched a small canoe to Rongo, although they built and used only rude craft for their fishing excursions. The canoe was manned by twelve figures symbolizing the personifications of the twelve months. Sometimes twenty-four figures were placed in the canoe, and Skinner interprets the additional twelve as representing the female counterparts of the months. As an old Maori once remarked. 'Everything has its female counterpart.'

... A curious diversion appears in the month list of the people of Porapora and Moorea in the Society Islands, which sheds light on the custom of the Moriori who sometimes placed 24 figures in the canoe which they dispatched seaward to the god Rongo on new years day. The names of the wives of the months are included, indicating that other Polynesians besides the Chatham Islanders personified the months ...

In rongorongo times heliacal 14h was probably at Tagaroa Uri 20, because in the times of Al Sharatain the stars rose 27 days earlier (293 - 27 = 266):

'March 24		Bluemarked stars are noted with their RA days in rongorongo times. (Both C and G below). Blackmarked stars are given with their nakshatra days = heliacal RA days ± 183.

Writing about C I had not yet realized that the creator of the text had followed the stars in their precessional advance forward in the solar year - instead of follwoing the Sun in his precessional advance earlier in the star year. Therefore I had not found any reason to use the Easter Island names. October 20 (293) above corresponds to Tagaroa Uri 20 (293) and to the Gregorian date ºOctober 16 (289), with the 4 days' difference in the day number due to the effects of the precession from the time of Gregorius XIII to rongorongo times.
