3. Suppose we should count to Rehua from raaraa in Gb6-20:

					65	183
Gb6-20 (*1)	Gb6-21	Gb6-22	Gb6-23	Gb6-24 (407)	248

Ga7-14 (184)	Ga7-15	Ga7-16 (*256)	Ga7-17	Ga7-18	Ga7-19
		64
Ga7-20	Ga7-21		Gb1-26 (256)	Gb2-1

If this method of counting was meant to be perceived by the reader, then we ought to find a midpoint 256 / 2 = 128 glyphs from Gb6-20:

					65	58
Gb6-20 (*1)	Gb6-21	Gb6-22	Gb6-23	Gb6-24 (407)	123
256 / 2 = 128

I have redmarked 123 as an important number, for instance in:

It is also the difference between 531 (= 3 * 177) and 408. Furthermore, it emerged (cfr at Tagata Gagana) as the number of glyphs from the beginning of side b to the last day of 354, i.e. 123 + 45 = 168:

In the discussion about the 'Sun Yolk' (cfr at The Rain God) I presented 21 glyphs and among them is kara etahi in Aa2-33 with ordinal number 123:

Aa2-28	Aa2-29	Aa2-30	Aa2-31	Aa2-32	Aa2-33	Aa2-34
Aa2-35	Aa2-36	Aa2-37	Aa2-38	Aa2-39	Aa2-40	Aa2-41
Aa2-42	Aa2-43	Aa2-44	Aa2-45	Aa2-46	Aa2-47	Aa2-48

It is probably significant to arrive at the beginning of the henua calendar (where 'land' is rising again) and to Rei in Ga2-27 as number 128 counted from Gb6-20:

Halfway from raaraa in Gb6-20 the henua calendar is initiated by Rei in Ga2-27 (where 22 divided by 7 generates π). Let us update with paint the first quartet of periods in my old table:

To make it work we have to combine 2 henua periods, which in a way is reassuring because the split personality of Mercury introduces number 2 so to say.

My play with structures and numbers must be supported by the images in the glyphs or else be dismissed. Here the key glyphs evidently are those I have suggested should belong to Mercury, because we recognize the head turned upside down and planted down in earth (poporo in Ga3-11) and the preceding hau tea has the eyes of Janus. It could be summer solstice.

Next we can count again and we are richly rewarded, because poporo is 'one more' than 140 days from raaraa and the distance 140 days (10 fortnights) has probably been calculated to be divided in half:

					65
Gb6-20 (*1)	Gb6-21	Gb6-22	Gb6-23	Gb6-24 (407)
70

69
	Ga3-10	Ga3-11 (*141)
70

70 days from what could be winter solstice the tablet must be turned around to side a, and then another 10 weeks are needed in order to reach the midpoint determined by Mercury. But this idea implies we must count 4 * 70 = 280 in order to complete the whole circuit. Support is given by the equation 472 - 280 = 192.

Thus we ought to continue to glyph number 70 + 140 = 210 (counted from Gb8-30):

Ga7-30 (200)	Ga7-31	Ga7-32	Ga7-33	Ga7-34

Ga8-1 (205)	Ga8-2	Ga8-3	Ga8-4

Ga8-5	Ga8-6 (210)	Ga8-7	Ga8-8	Ga8-9

Ga8-10 (214)	Ga8-11	Ga8-12
Ga8-13	Ga8-14	Ga8-15

In Ga7-32 there are 7 + 6 = 13 feather signs - could they represent the 'tail feathers' of the year? Hardly, there should be only 2 of them. Maybe they instead are represented by glyph lines a8 and b1 because both have 26 glyphs and glyph number 256 counted from the beginning of the front side is the last in line b1:
