According to my scheme the 3 periods 5-7 are beginning with such ordinal numbers in the line which 'are ruled by Saturn', and then the 8th period is instead beginning with a Mercury number:

8
	Ca8-22	Ca8-23	Ca8-24	Ca8-25	Ca8-26 (225)
	October 28 (301)	29	30	31	November 1

Ca8-27	Ca8-28	Ca8-29	Ca9-1	Ca9-2 (230)
November 2	3	4	5	6 (310)

We recognize the type of triplet at the end of line a8 from line a5 and 104 glyphs earlier:

The calendar of the Moon is ending with glyph 230, a support for my method to count the front side of the G text from Gb8-30. Side a ends with glyph 230.

Half 472 is 236 and from there to next glyph on the G tablet there is a turning around. In the C text glyph 237 describes a break (koti):

Ca9-3	Ca9-4	Ca9-5	Ca9-6	Ca9-7	Ca9-8 (236)
November 7	8	9	10 (314)	11	12

Ca9-9	Ca9-10	Ca9-11	Ca9-12	Ca9-13	Ca9-14 (242)
November 13	14	15	16	17 (321)	18

Ca9-15	Ca9-16	Ca9-17	Ca9-18	Ca9-19	Ca9-20
November 19	20	21 (325)	22	23	24

Ca9-21	Ca9-22	Ca9-23	Ca9-24	Ca9-25	Ca9-26
November 25 (329)	26	27	28	29	30

Ca9-27 (255)

December 1 (335)

November 25 is the day when Antares was rising heliacally in rongorongo times. From Ca9-21 a new type of glyph appears, viz. a variant of inoino with 'eyes' (mata):

Hakaariki in Ca9-27 is the last glyph in the line. It has the kai sign in front, in contrast to the earlier hakaariki:

There are 172 days from January 1 to the northern midsummer and perhaps this fact motivated the creator of the Mamari text to use this distance.
