There should be some kind of relationship between the wavy wing sign and ua glyphs.

Ordinal number 29 (and - we can infer - 129) indicates the dark new moon night, not in disharmony with how we have interpreted ua glyphs so far. The only ua glyph in K was number 29 counted from Kb1-14 (viri at the beginning of the 2nd half up to the 'gnomon' at 100).

36 at ua in Eb5-16 (counted from the 2nd of the wavy wing birds) could mean the 1st half (of the 2nd half) is finished (according to how there are 36 glyphs in each half of the Mamari moon calendar).

36 does not necessarily point at the 360 days in a regular sun year. Together with ordinal number 16 in line Eb5 the reading is more likely to be the end of a growing moon season, presumably 210 nights long.

In K ua was glyph number 3 * 36 = 108 (counted beyond the 1st Rei) and the structure of the K text indicates ua stands at the end of the sun (108 = 6 * 18), beyond which 6 * 14 = 84 glyphs for the moon follows.

What seems clear is that ua marks the end for the 'sun' ('summer') season.
