The figure at the top end of the oval in Ca7-24 surely is a kai person, and the position high up could mean he has arrived as high as he can. The eating cannot go on any longer and he is therefore depicted as if he had entered inside (uru) a cavity, I think. A crack in time is evidently illustrated both by the broken beam at bottom and by the open space between them and the figure up high. I have a glyph type named koti ('broken') and it normally shows a vertical break:


Ca7-24	koti

Koti

Kotikoti. To cut with scissors (since this is an old word and scissors do not seem to have existed, it must mean something of the kind). Vanaga.

Kotikoti. To tear; kokoti, to cut, to chop, to hew, to cleave, to assassinate, to amputate, to scar, to notch, to carve, to use a knife, to cut off, to lop, to gash, to mow, to saw; kokotiga kore, indivisible; kokotihaga, cutting, gash furrow.

The full moon night is Omotohi (no more 'sucking', omo). The oval sign could indicate a stop, a restraint (tohi):

Omo

To suck; omoaga, bulky cloud; ragi omoaga cumulus; omoomo; to suck repeatedly, to suckle; omotahi, to win everything at a game (lit: to suck whole): omotahi-mai-á e au, he has cleaned me out; omotohi, full (of the moon); ku-omotohiá te mahina, the moon is full. Vanaga.

Possibly also Ga1-16 has an oval depicting the full moon, because according to the previous discussion its number could be 13, and at new year it should be a full moon night, at least it was so on Hawaii (where also a ceremony of 'breaking' took place):

... The correspondence between the winter solstice and the kali'i rite of the Makahiki is arrived at as follows: ideally, the second ceremony of 'breaking the coconut', when the priests assemble at the temple to spot the rising of the Pleiades, coincides with the full moon (Hua tapu) of the twelfth lunar month (Welehu). In the latter eighteenth century, the Pleiades appear at sunset on 18 November. Ten days later (28 November), the Lono effigy sets off on its circuit, which lasts twenty-three days, thus bringing the god back for the climactic battle with the king on 21 December, the solstice (= Hawaiian 16 Makali'i). The correspondence is 'ideal' and only rarely achieved, since it depends on the coincidence of the full moon and the crepuscular rising of the Pleiades ...

On the other hand, the pattern from Ga1-5 up to and including Ga1-14 suggests another distribution, which will put Ga1-16 in position number 15:
