The first page about a possible 496-day year:

A square measured out as 4 by 61 days for the first half of the year comes after 8 * 29.5 = 236 (Te Pei at Gb1-6). Sun is measured by 4 and moon by 8: Gb1-5 Gb1-6 (236) Gb1-7 Gb1-8 Gb1-9 Gb1-10 Gb1-11 Gb1-12 Gb1-13 Gb1-14 (244) Gb1-15 Gb1-16 Gb1-17 Gb1-18 Gb1-19 If spring sun is finished after 244 days, there could follow 2 moon 'years' each with 8 by 8 = 64 days. 244 + 64 + 64 = 372 = 12 * 31: Gb5-6 (360) Gb5-7 Gb5-8 Gb5-9 Gb5-10 Gb5-11 Gb5-12 (366) Gb5-13 Gb5-14 Gb5-15 Gb5-16 Gb5-17 Gb5-18 (372) Gb5-19 Gb5-20 Gb5-21 Gb5-22 Gb5-23 (377) Moa in Gb5-19 cries out, for a new year is being born.

I suspect yet another year is measured out by 377 = 13 * 29. Gb5-22 is identical with Gb5-17, and 5-22 says the 'fire' has come to the end of its cycle. 29 'carries darkness'.

There are 4 glyphs between Gb5-17 and Gb5-22, also between Gb5-23 and the equally dark Gb5-28:

Gb5-23	Gb5-24	Gb5-25	Gb5-26	Gb5-27 (381)	Gb5-28

In between is kava announcing new fire (5-25), followed by an eating moa. Tagata at Gb5-27 has number 381 = 3 * 127, and 14 * 27 = 378 is at Gb5-24, a very remarkable glyph.'

Possibly there is a relation between Gb5-8--9 and Gb5-24:

Gb5-6 (360)	Gb5-7	Gb5-8	Gb5-9	Gb5-10 (364)	Gb5-11
Gb5-12	Gb5-13	Gb5-14	Gb5-15	Gb5-16
Gb5-17	Gb5-18	Gb5-19	Gb5-20	Gb5-21
Gb5-22	Gb5-23	Gb5-24	Gb5-25	Gb5-26	Gb5-27

The relationship should be that the dancing triplet in Gb5-24 represents the new year while the distorted 2 + 1 represent the old year - the distribution is like that in Aa8-80 (708, Hatinga Te Kohe, 12 * 29.5):

ki to hatu huri

Maybe a dancing triplet suggests the time when a new 'king' is created? Metoro said e gagata hakaariki at Ca4-7:

Ca4-1	Ca4-2	Ca4-3	Ca4-4	Ca4-5	Ca4-6	Ca4-7

Likewise etoru gagata hakaariki kia raua at the end of glyph line Ca9:

Ca9-21	Ca9-22	Ca9-23	Ca9-24	Ca9-25	Ca9-26	Ca9-27

Nowhere else did he say hakaariki. In view of the pattern with 6 glyphs followed by a dancing triplet in the first sequence of glyphs at the beginning of line a4 and a second at the end of line a9, as if serving to mark the 5 glyphs lines a4 - a9, we should count:

179 is a prime number and says nothing. If we reduce by 6 + 6 we get the well known 167. 392 - 167 = 225 = 15 * 15 = 9 * 25.
