Maybe 22 is not only 7 * π, but also something else. It may mean '2 and 2', indicating that the year has two halves and that each half is divided in two parts (quarters).

When in G Te Pei comes on side b it does not come as Gb1-1 but as Gb1-7, as number 17 counted from Ga8-17. As number 22 comes Gb1-12:

Ga8-17 (221)	Ga8-18	Ga8-19	Ga8-20	Ga8-21
Ga8-22 (226)	Ga8-23	Ga8-24	Ga8-25	Ga8-26
Gb1-1 (231)	Gb1-2	Gb1-3	Gb1-4	Gb1-5
Gb1-6 (236)	Gb1-7	Gb1-8	Gb1-9	Gb1-10
Gb1-11	Gb1-12 (242)	Gb1-13	Gb1-14	Gb1-15
Gb1-16 (246)	Gb1-17	Gb1-18	Gb1-19	Gb1-20
Gb1-21 (251)	Gb1-22	Gb1-23	Gb1-24	Gb1-25 (255)

We should take the chance to note the different signs used for procreation:

 

Ga8-17	Ga8-26	Gb1-1	Gb1-5	Gb1-7	Gb1-4
Gb1-8	Gb1-10	Gb1-12	Gb1-15	Gb1-20	Gb1-23

These 12 signs, occuring within a space of 32 glyphs (counted long), in a way identify the beginning of the story on side b, because not a single ure sign comes before Ga8-17, but I have a total of 41 ure glyphs listed in the catalogue.

Significantly none is to be found in K. Procreation does not occur on 'land' but in the 'sea'.

The last glyph before Ga8-17 is number 220 (= 10 * 22). Let us map the glyphs from the end of 'light' to the beginning of 'procreation':

 

Ga7-11	Ga7-12 (182)	Ga7-13	Ga7-14	Ga7-15	Ga7-16
Ga7-17	Ga7-18 (188)	Ga7-19	Ga7-20	Ga7-21	Ga7-22
Ga7-23	Ga7-24 (194)
Ga7-25	Ga7-26	Ga7-27 (197)	Ga7-28	Ga7-29	Ga7-30
Ga7-31	Ga7-32	Ga7-33 (203)	Ga7-34
Ga8-1	Ga8-2	Ga8-3	Ga8-4	Ga8-5	Ga8-6 (210)
Ga8-7	Ga8-8	Ga8-9 (213)	Ga8-10	Ga8-11	Ga8-12
Ga8-13	Ga8-14	Ga8-15	Ga8-16 (220)

The text of G seems to be rather insensitive to 7 * 29.5 = 206.5, and if we didn't know from counting where to find it we would not find it. But it makes sense, in a way, because moving from Nga Kope Ririva further west there is no land.

Nga Kope Ririva seems to be the place where the necessary renewal takes place, and it ends - I think - with Ga7-24 (196). 8 glyphs are measured out for the islets. 7 * 24 = 168. 196 = 7 * 28 = 14 * 14. 6 * 29.5 = 177 is where we should look for the first signs of Nga Kope Ririva, if the kuhane journey is to be relied upon:

I have suggested the maitaki glyph type to be associated with the 3 islets, and I have 26 such glyhs at G in the catalogue, and a symmetric pattern is discernible:

Ga1-17	Ga1-21	Ga3-11	Ga3-17	Ga4-20	Ga5-5
		8
Ga5-10	Ga5-13
					10
Ga7-8	Ga7-14	Ga7-18	Ga7-19	Ga7-24
Ga8-6	Ga8-10	Ga8-17	Ga8-21	Ga8-26
Gb2-22	Gb4-3	Gb4-26	Gb4-27	Gb6-5	Gb7-23
		8
Gb7-30	Gb8-17

I guess Ga7-18 and Ga4-20 illustrate the mainland (3 fused rhombs at bottom) with Nga Kope Ririva (at the top). Or could it be the reverse?

Ga4-20 (104)		Ga7-18 (190)
