In G glyph numbers are counted from Gb8-30, in A from Ab8-41:
Te Pei 8 * 29.5 = 236
	Gb1-6 (236)	Gb1-7	Aa6-10	Aa6-11 (472)	Aa6-12	Aa6-13
Te Pou 9 * 29.5 = 265.5
	Gb2-10 (266)	Gb2-11	Aa6-69	Aa6-70 (531)	Aa6-71	Aa6-72
Hatinga Te Kohe 12 * 29.5 = 354
	Gb4-33 (354)	Gb5-1	Aa8-77	Aa8-78 (708)	Aa8-79	Aa8-80

In order to accomplish a structure which is parallel with G I have here revised the counting in A to begin neither from pito (Ab8-43) nor from ihe tau (Ab8-44) but from nuku at Ab8-41:

Ab8-39	Ab8-40	Ab8-41 (1)	Ab8-42
day zero		day 1
Ab8-43	Ab8-44	Ab8-45	Ab8-46
day 2		day 3

Aa8-80 (where 8 * 8 = 64) is not of the standard koti type because, I suggest, Hatinga Te Kohe is a lunar measure.

In G the reversal comes with day 354 + 1, and in Tahua a koti glyph (Aa8-80) marks the 2nd half of day 354 + 1.

Day zero, I guess, is equal to day (1334 + 2) / 2 = 668 = 368 + 300. In G we have to count a day twice and this rule seems to apply also to Tahua. 1336 can be read as 'thirten 36' (which happens to be 468, and then we can count 46 * 8 = 368).

Day 368 can be identified by counting from Ab8-41:

Hanga Te Pau 366
	Ab1-10	Ab1-11	Ab1-12	Ab1-13	Ab1-14	Ab1-15
	363		364		365
	Ab1-16	Ab1-17 (732)	Ab1-18	Ab1-19	Ab1-20	Ab1-21 (736)
	day 732 / 2 = 366		367		day 736 / 2 = 368

According to Manuscript E the explorers had to go back to Hanga Te Pau in order to fetch fire. The first half of day 366 is a mauga glyph (meaning darkness), but in the 2nd half 2 + 5 'feathers' indicate fire.
