Furthermore, even if we knew with certainty how the beginning of side a on the C and the G  tablets were to be understood it is not certain that the glyphs all through the texts have to be read as either heliacal or nakshatra, the view could change e.g. at Spica.

Counted from September 20 (Ca1-1) Spica should be 163 + 120 = 283 days ahead:

162	Heka (163)	119	Spica (283)	82
365

And then we have on side b found Spica at the great vero with a great dot in front:

9			3		161		171 = 9 * 19
	Cb1-10	Cb1-11 (403)		Cb1-15 (407)		Cb8-6 (569)
	ka higa te ao ko te henua ra ma te hoi atua			e niu tu		vero hia
					162 = 6 * 27
	168 = 7 * 24

With moa in Cb4-21 resembling moa in Cb1-11 (neither of them with beak open) we ought to count the distance between them and in glyphs it is 484 - 403 = 81 (possible reflecting the day number of March 22):

There ought to be some relation between them, because they are similar. The following are all moa I once classified in the C text (and on side b all of them have their beaks closed):

Counting at the great vero in Cb8-6: 569 + 183 - 2 * 365 = RA day 22 means this cannot be the place for heliacal Spica (and Algol). To make it fit we need to change from heliacal to nakshatra view:

October 27	28 (301)	3	November 1	161	April 12 (102)
Cb1-10	Cb1-11 (403)		Cb1-15 (407)		Cb8-6 (569)
ka higa te ao ko te henua ra ma te hoi atua			e niu tu		vero hia
Haris (219.7). σ Bootis (220.2), η Centauri (220.4)	ρ Lupi (221.0), Toliman (221.2)		Kochab (225.0)		no star listed
			Right Wing (40.9), π Arietis (41.2),  BHARANI (41.4)
no stars listed					SPICA, Alcor (202.7)

Maybe the heliacal view could end with glyph 403 and Toliman, or at some other place before reaching Cb8-6. Or maybe the view changes at Spica and Alcor.

403 (Cb1-11) = 392 (side a) + 11. In G glyph 403 is very special and then follow 4 glyphs which could illustrate the idea of back side, and then another 4 which are showing their facial side:

Gb6-17	Gb6-18	Gb6-19	Gb6-20 (403)

Gb6-21	Gb6-22	Gb6-23	Gb6-24 (407)

Gb6-25	Gb6-26	Gb6-27	Gb6-28 (411)

Applying our rule of thumb also in the G text we could count 403 + 183 - 365 = RA day 221 (October 28). We have earlier found Rogo in Gb6-26 to be at March 21 (0h). But 409 + 183 - 365 = RA day 227 (November 3), where 227 could be a sign of π.

We can compare with the 8 days following Cb1-11 (403):

April 28	29	30 (120)
Cb1-12	Cb1-13	Cb1-14
manu rere - kua rere ga manu - ki te ragi	eaha te nuku erua	koia kua huki
ν Arietis (38.5)	μ Arietis (39.4)	Head of the Fly (39.6), Kaffaljidhma (39.8), ο Arietis (40.01),  Angetenar (40.2)
October 29	30 (303)	31
π Bootis (221.8), ζ Bootis (221.9), 31 Bootis (222.0), Yang Mun (222.1), Rijl al Awwa (222.5)	ο Bootis (222.9), Izar (223.0), 109 Virginis (223.3)	Al Zubānā-14 / Visakha-16 / Root-3
		ZUBEN ELGENUBI (224.2), ξ Bootis, ο Lupi (224.5)
