Once again:

Qa6-16	Qa6-17 (222)	Qa6-18	Qa6-19	Qa6-20
Qa6-21	Qa6-22	Qa6-23	Qa6-24	Qa6-25 (230)
Qa6-26	Qa6-27	Qa6-28	Qa6-29	Qa6-30
Qa6-31 (236)	Qa6-32 (237)	Qa6-33	Qa6-34	Qa6-35 (240)
Qa6-36	Qa6-37	Qa6-38	Qa6-39	Qa6-40
				...
Qa6-41	Qa6-42	Qa6-43	Qa6-44	*Qa6-45 (250)

There is much food for thought here. At *Qa6-45 the text is disappearing, hardly a coincidence because of the ordinal number (and 6 * 45 = 270).

250 / 2 + 64 = day 189, one week beyond day 182 = 364 / 2. One week is also measured out by tagata lifting both hands:

				10
Qa6-26	Qa6-27 (232)	Qa6-28	Qa6-29		Qa6-40	Qa6-41 (246)	Qa6-42	Qa6-43
232 / 2 + 64 = 180		181		5	187		188

The special henua type in Qa6-42 we recognize from the day of Saturn, and 6-43 is there reversed into 436:

Hb9-51	Hb9-52	Hb9-53 (1113)	Hb9-54	Hb9-55	Hb9-56
(1113 - 3) / 3 + 64 = 434			435

Hb9-54	Hb9-55	Hb9-56	Hb9-57 (1117)	Hb9-58	Hb9-58
435			436 (= 368 + 68)

A close scrutiny reveals that Qa6-42 seems to be turned upside down compared with Hb9-57:

Qa6-42	Hb9-57

6 * 42 = 7 * 36 (as we know from the discussion of the 7th flame of the sun).

9 * 53 = 513 we also recognize:

531 = 18 * 29.5, another final measure for the sun. If we count with 2 glyphs per day 531 will point at Te Pou. And with 3 glyphs per day 531 will be 177 days, half 354. 531 must be an important constant for calendar makers.

The only somewhat similar henua of this irregular type is *Qa2-19, and significantly it has ordinal number 42:

368 + 85 = 453. If we count with 369, it will be 454, which we can read as 45 * 4 = 180. Or maybe we should count 4 * 54 = 216? At any rate, 144 + 225 = 369 is - it appears - a necessity.
