There seems to be cardinal points in the vicinity of both tagata at Gb5-6 and henua at Ga5-2:

5 * 6 = 30 and 5 * 2 = 10. Or, 56 = 2 * 28 = 4 * 14 and 52 = 2 * 26 = 4 * 13.

Let us try with another obvious cardinal marker, viz. manu kake in Ga4-21. It is glyph number 105 counted from Gb8-30, i.e. it should have a corresponding glyph in position 472 - 104 = 368 (indeed a number which probably marks a cardinal point):

The 3 identical fishes have each a 'feather' sign inside, not visible on the outside, i.e. presumably they are meant to be not light but black.

But on the other side of the tablet, on side a (the front side of the tablet) the glyphs which are preceding manu kake (in Ga4-21) evidently are in a season bathing in sun light. Another manu kake stands at its beginning, in period number 1 after the 'ignition' by the 'fire generator' (haga in Ga2-26):

Ga2-21	Ga2-22	Ga2-23	Ga2-24	Ga2-25	Ga2-26

1
	Ga2-27	Ga2-28	Ga2-29 (60)
	Ga3-1	Ga3-2	Ga3-3	Ga3-4	Ga3-5

368 - 4 = 364 (vaha kai in Gb5-10) and if we add 4 to 105 it becomes 109:

From which we can expect henua in Ga4-25 to also be important.
