Manu rere in Aa5-9 has a curiously formed right wing, similar to that in the last glyph of line a2:

165
Aa2-85 (175) Aa5-8 Aa5-9 Aa5-10 Aa5-11 (344)
168

No other manu rere in Tahua has this sign. Kara etahi in Aa5-10 therefore indeed appears to be at the end of 'summer', because 364 - 168 = 196 evidently is a number for 'winter'. 'Fire' (5) has reached to its end (10).

The structure of Tahua suggests that the last glyph in line Aa2 could indicate when it is time for spring Sun to return. 175 at Aa2-85 is equal to 7 * 25 as in Ab7-25.

The first of the manu rere glyphs which on side a have an 'open' left wing comes 5 glyphs later:

Aa2-81 Aa2-82 Aa2-83 Aa2-84 Aa2-85
Aa3-1 Aa3-2 Aa3-3 Aa3-4 Aa3-5 (180)

Moving on, we will reach 4 manu rere glyphs with various 'open' wings:

Aa3-56 (231) Aa3-57 Aa3-58 Aa3-59 Aa3-60
Aa3-61 (236) Aa3-62 Aa3-63 Aa3-64

236 suggests 8 * 29.5 and these 4 birds are looking high. 3 * 64 = 192, and a little 'egg' in front forms the 'thumb' of the 'tree'.

Time moves on into a new phase and Metoro mentioned matagi (wind, tempest etc) at Aa3-65 (probably alluding to day 365).

Aa3-65 (240) Aa3-66 Aa3-67 Aa3-68 Aa3-69 Aa3-70 Aa3-71 (246)

Rogo in Aa3-67 could refer to summer solstice. Possibly there is an order which has this Rogo as glyph number 3 beyond Aa3-64 (similar to his number 363 = 360 + 3 as for instance in the text of C). 242 - 183 = 59 indicates the probability of a lunar double month at the beginning of side a.

Kara etahi in Aa5-10 is glyph number 99 + 2 beyond Rogo and 343 - 183 = 160:

98
Aa3-67 (242) Aa5-8 Aa5-9
Aa5-10 (343) Aa5-11 Aa5-12 Aa5-13

99 can also be exposed by counting 1334 - 346 (at Aa5-13) = 988, and then 9 * 88 = 792 (= 192 + 600) = 8 * 99. Beyond Aa5-13 it might be Venus who will be our star of guidance rather than the sun:

525 80 525 138 64
Aa8-5 (590) Ab7-30 (526)
526 808 = 8 * (99 + 2)
239
Aa5-8 Aa5-9 Aa5-10 Aa5-11 (344) Aa7-84 (584)

808 can be read as a map of the structure: 8 periods will reach to the end of the cycle (0) and then another 8 periods will follow. The perspective presumably is that 0 is at midsummer, where the 'egg' (0) is produced.

By 'coincidence' number 505 (where the Moon measure 8 has been changed into the Sun measure 5) appears if we count only on side a:

327 176
Aa5-10 (343) Aa2-85 (175)
505

5 is 'fire', yet 6 is needed to reach to the end of the year (6 * 30 = 180 for instance). Between 8 and 6 there is room for 2 more. We can postulate the existence of a lunar double month at the beginning of side a and then - for symmetry reasons - also 59 such extra glyphs on side b. 1334 - 59 - 59 = 1216, which is a beautiful number incorporating both Sun (12) and Moon (16).

Furthermore, 12 * 16 = 192 will serve as a symbol for the time of light. Such a good number as 1216 ought to be turned this way and that, to really appreciate it. For instance is 1216 = 1000 + 6 * 6 * 6. The number of glyphs on side a of H can (among other alternatives) be reconstructed as 666, and 666 ('the number of the beast') probably is alluded to in Aa6-66:

Aa6-64 Aa6-65 Aa6-66 Aa6-67 Aa6-68 Aa6-69 Aa6-70

216 (= 360 - 12 * 12 = 12 * 18 = 384 - 168) has evidently been used also in the H text, because 648 is probably the number of glyphs on side b and 648 becomes the number of glyphs also on side a if we reduce 666 with 18 (corresponding to an estimated number of glyphs beyond Ha12-21). 648 / 3 = 216.

The number of glyphs in P is 599 on side a, possibly expressing 'fire' and 99 (Venus). The estimated number on side b is 559, probably a 'mirror image' of 599. Rotating 6 it becomes 9.
