'Feathers' on both sides presumably should be read as 'occulted'. In Ga7-25 the first of the Rogo glyphs has at left a limb with 6 + 6 = 12 'feathers'. Maybe each such means 15 days - 12 * 15 = 180.

In Ga7-32 there are, in the figure at left, 7 + 6 = 13 'feathers'. 13 * 15 = 195, possibly referring to glyph number 195 (Rogo in Ga7-25). Maybe 195 is another day of Rogo (in addition to day number 363). 363 - 195 = 168 (a wellknown rongorongo number).

Ika hiku in Ga7-27 has 4 + 3 'bent feathers', maybe meaning 'weak'. 7 days in a week times 27 = 189 days, which could refer to Ga7-19:

Ga7-18	Ga7-19 (189)	Ga7-20	Ga7-21	Ga7-22 (192)
Ga7-23	Ga7-24	Ga7-25	Ga7-26	Ga7-27 (197)

7-19 is like a 'reversed' 197. 7 * 19 = 19 * 7 = 133. Maybe this number is related to 261 (= 9 * 29), because 133 + 2 * 64 (cfr later). Furthermore, 133 + 261 = 394 = 2 * 197.

If we think of ika hiku (the 'shark egg') as similar to rau hei, then a rising shark 197 days later is not difficult to understand:

Gb6-5	Gb6-6	Gb6-7 (390)	Gb6-8	Gb6-9	Gb6-10
Gb6-11 (394)	Gb6-12	Gb6-13	Gb6-14	Gb6-15	Gb6-16 (399)

Day 197 in Q is also telling about a rising shark:
