The number of glyphs on side b is 348 = 12 * 29 and at the great vero in Cb8-6 there is a great dot in front at the bottom:
Above I have adjusted the position of Achernar (α Eridani) from Cb8-8 to Cb8-9, because 23.3 + 182½ = 205.8 is at the opposite side (where October 13 = 286 = 80 + 206). Then the glyph for October 13 becomes reasonable - it means that ihe tau is over (in the past). In October 13 spring was an established fact on Easter Island. In Cb8-10, however, the reversed ihe tau maro maybe should be read in connection with Cb8-11 and the rest of the 12 pairs of ihe tau glyphs. Which will have to wait for a while. At heliacal Spica Metoro said vero hia and counted is what I just have begun to do:
740 - 569 (Cb8-6) = 171 is not a multiple of 29, but possibly we should count 741 - 569 = 172 (June 21), as an allusion to the middle of summer north of the equator. However an extra day for March 21 would affect also the glyph number at vero: 741 - 570 = 171 (= 9 * 19 = 39 * 19 - 30 * 19). I.e. vero hia could mean for instance 19 months with 30 days in each or 30 periods with 19 days in each. 29 could allude to the dark night of the Moon when she is rejuvenated and 49 could allude to how Sun is preparing for his comeback in day 50: ... When the new moon appeared women assembled and bewailed those who had died since the last one, uttering the following lament: 'Alas! O moon! Thou has returned to life, but our departed beloved ones have not. Thou has bathed in the waiora a Tane, and had thy life renewed, but there is no fount to restore life to our departed ones. Alas ... ... the heliacal rising of Algenib Persei occurred (in rongorongo times) in RA day 50.0 (i.e. May 10, which can be written 5-10) ... When Sun was at the other side of the Moon, shining on her back, it was night number 29, and then, in the following fortnight, she was gradually swelling, and her 'pregnancy' resulted in a 'fruit' (O-hua, offspring):
Another possibility could be to count in multiples of 13, but that appears to give no satisfactory result. 13 * 13 = 169 (< 171) and 14 * 13 = 182 (> 171). The component 57 (= 3 * 19) is though equal to 171 / 3. And 285 * 2 = 570 (= 569 + 1). There could be a hint here to count with months equal to 28½ days. 741 = 26 * 28½. And then 570 / 28½ = 20. When Spica rose with the Sun in October 10 (= 8 * 10 or 10 * 10), then there were 20 times 28½ days from the origin of the text at ·. From October 10 to the end of the text there were 741 - 570 = 3 double-months with 57 days in each. 283 (October 10) + 3 * 57 = 454 (= 12 * 29½ + 100). Counting 171 days ahead from April 11 (101 in a regular year and 102 in a leap year) means we will reach day 171 + 101 (or 102) = 272 (or 273). The circumstances are such that we ought to count April 11 as day 102 because then the end of side be will be at September 30. This should be the final day of Sun north of the equator. South of the equator the end of side b ought instead to be at the end of March.
