Now there are many ideas whirling around. First a little note considering 'the zero season of sun' in K:

The 3-fingered tail feathers of moa in Ka3-19 may be the same type of sign as the hand hiding the light in e.g. Kb5-15:

Altough the 'thumb' has been shifted to the left.

5 * 13 = 65 could mean the 'fire' is 'liquidated'.

Next, I have decided to take up the 'Twin Quarters' (according to G and K) in an excursion at the end of the maitaki chapter. It leads potentially to several interesting questions and conclusions.

'Dark' (uri) means 'greenery', but to have such growth the rains from heaven are necessary. The sky must become dark (clouded) first.

"The Timorese sacrifice a black pig to the Earth-goddess for rain, a white or red one to the Sun-god for sunshine." (The Golden Bough)

The islands in the Pacific have their eastern half as 'black' and their western half as 'white' (like old dry bones).

The double necessities (sunshine and rain) are not contradictory forces, they are allied in creating growth.

A piece of bamboo has both qualitites, it can burn and it can hold fluid.

Maybe we should shift Te Kioe Uri and Te Poko Uri two steps (2 * 29.5 = 59 days) ahead in G? Wouldn't it be good to get rid of Nga Kope Ririva?

Or should we change their order into:

If we manage to understand the design of maitaki in Ga7-8, this problem presumably would be solved.

Uri should anyhow come after the 'fire' ('flames lifting up the sky roof'). Tangaroa Uri is said  to be October ('April') and the greenery comes at the beginning of summer. Before that Mars will raise the sky roof.

The 3 rocks standing upright in the water are, maybe, responsible for pushing the sky roof up. They should then be standing upright before the rain arrives, before Ga5-8 according to the measures 4 * 66 and 4 * 52:
