... Sun is fire (and light and life) incorporated and cannot tolerate water, which 'kills' him. Into the western ocean he descends and it becomes black. In the text of K he is alive up to 168, and then only his spirit continues. But the watery stretch between the mainland and Nga Kope Ririva cannot have any glyph ...

						...	19
Kb4-14	Kb4-15	Kb4-16	Kb4-17	Kb4-18	Kb4-19	*Kb5-1	19
167	168	169	170	22

However, at position 168 another important light in the sky, the new waxing moon, would be perfectly located. And that is exactly what we can read in the Mamari moon calendar - after position 167 the great Moa cries out that a new moon is 'dawning'.

The period described by 167 glyphs presumably refers only to such nights when moon (potentially at least) is visible. 6 * 29.5 = 177 could then be the total length of the 'sun-is-present' season. Somewhere among the 3 islets (Nga Kope Ririva) is the definite final.

Furthermore, the 'shield' at right in Kb4-17 may indicate (by way of its internal signs) that a 'pivotal point' is reached at 170. Maybe an attempt has been made to define the length of the regular solar calendar year as 360 days:

170 / 167 * 12 * 29.5 = 360.36

Supporting evidence is given by the fact that beyond Kb4-17 there are 22 glyph positions remaining - and 22 probably refers to π by way of 22 / 7. The circumference of a cycle is 2 * 22 / 7 times the radius. The measure of half a cycle is 22 / 7 times the radius. So, 'half the cycle (of the year) remains beyond Kb4-17' could be the message.

The mea ke sign in Kb4-17 should make us reconsider, because the sign presumably indicates winter solstice. Let us therefore assume that each glyph in K stands for 2 days and see where this assumption leads us.
