The problem with Rei glyphs is that they are too frequent - because of that they cannot function as reliable markers.

The table is encouraging but not convincing.

In G, the text which is best known for us so far, there are 7 well ordered mago glyphs, and Ga7-16 sits where we can find only an imaginary parallel glyph in K:

Ga2-14	Ga3-23	Ga7-16
Gb6-11
Gb6-13	Gb7-13	Gb7-16

Ga7-15	Ga7-16	Ga7-17
	...
Kb4-19		*Kb5-2	*Kb5-3

Obviously Ga7-16 is located at an important point. It is located at the beginning of Nga Kope Ririva (which is beginning in the last one of the kiore + henua periods):

 

Ga7-5	Ga7-6	Ga7-7	Ga7-8	Ga7-9	Ga7-10
175	176	177	178	179	180

Ga7-11	Ga7-12	Ga7-13	Ga7-14
181	182	183	184

Ga7-15	Ga7-16	Ga7-17
185	186	187

Now I have counted from the last glyph on side b, and 6 * 29.5 = 177 becomes the feathery henua ora in Ga7-7. It says, though, that there are 8 periods at left and 8 at right. Maybe it refers to the situation at Te Pei?

The tail at right in Ga7-16 is the standard direction not only for mago but also for other glyph types. In Ga7-13 a cycle is closing at left and the bottom part is drawn as if to focus the attention of the reader - perhaps to allude to the switch of direction taking place.

The ordinal numbers (7-7 etc) tell we have done right by counting from Gb8-30. 177 is half 354 and 180 half 360, quite in order because the first cycle of the sun ends here.

183 * 2 = 366 at Ga7-13 and the tagata rere sign confirm each other. In Ga7-14 the 'sails' are in the past (at left).

In A there is only one glyph which closely resembles Ga7-16:

Aa4-29	Aa6-28	Aa6-70	Aa8-12	Aa8-37	Aa8-83
Ab3-40	Ab3-44	Ab3-67	Ab4-73	Ab4-74

The location of Aa8-12 is though neither at day 186 nor at day 366 (or 372) - neither in Nga Kope Ririva (6 * 29.5 = 177) nor in Hatinga Te Kohe (12 * 29.5 = 354), but in Hua Reva (10 * 29.5 = 295):

 

Aa8-2	Aa8-3	Aa8-4 (590)	Aa8-5	Aa8-6	Aa8-7	Aa8-8	Aa8-9
Aa8-10	Aa8-11	Aa8-12 (598)	Aa8-13	Aa8-14	Aa8-15	Aa8-16	Aa8-17
Aa8-18	Aa8-19	Aa8-20	Aa8-21	Aa8-22	Aa8-23	Aa8-24	Aa8-25

We cannot trust less frequent glyphs either. But we can recognize that Aa8-12 may mean something like 'sun has been swallowed'. The surrounding ua glyphs confirm we are in Hua Reva. The kuhane stations seem to be reliable as guidance in A.

Aa6-70 in Te Pei (8 * 29.5 = 236) is located in a surrounding with vai glyphs. Its mouth is closed and the ua glyphs are adorned with 'eye crests' or have been reversed (Aa6-66):

 

Aa6-50	Aa6-51	Aa6-52	Aa6-53	Aa6-54	Aa6-55 (472)	Aa6-56
Aa6-57	Aa6-58	Aa6-59	Aa6-60	Aa6-61	Aa6-62	Aa6-63
Aa6-64	Aa6-65	Aa6-66	Aa6-67	Aa6-68	Aa6-69	Aa6-70 (487)
Aa6-71	Aa6-72	Aa6-73	Aa6-74	Aa6-75	Aa6-76

In G there are two similar mago glyphs (with mouths closed):

Ga2-13	Ga2-14 (45)	Ga2-15	Ga2-16	Ga2-17	Ga2-18	Ga2-19
Ka3-1	Ka3-2 (48)	Ka3-3	Ka3-4	Ka3-5	Ka3-6	Ka3-7

Ga3-22	Ga3-23 (83)	Ga3-24
Ka4-13	Ka4-14 (81)	Ka4-15

The closed mouth should mean the opposite of the open mouth - there is a turn into sun light. Ka4-15 initiates a season with a broad henua. Aa6-70 is positioned at the beginning of the 2nd cycle of the sun, when he is 'abroad', but there are feathers which lighten up.

In Ga2-14 at 45 the half wedge sign inside the head of mago could say 'half' - implying 45 is ½ * 90. Ga4-6 is number 90:

 

8		9
Ga4-5	Ga4-6 (90)	Ga4-7	Ga4-8
Ka5-2	Ka5-3 (86)	Ka5-4	Ka5-5

The first three glyph lines in G measure up 84 days (if Gb8-30 is counted). In K the first four glyph lines measure up 83 days, possibly an indication we should add an extra glyph at the beginning of the K text.
