The problems are getting more and more complex, not only do we have a reversal at Kb1-10--11 (evidenced by how the 'sails' have changed from Kb1-9 to Kb1-13) - in competition with Kb1-6--7 of being in the 'center' - but we shouldn't forget at third candidate, Ka5-14 (the lifeless Rei):

 

One possibility is to regard the center to be a long sequence of glyphs, incorporating all three candidates. This alternative presumably necessitates a sequence with 18 (a nice sun-oriented number for half a year):

 

Another approach is to limit the investigation about the structure of the calendar in K to the 29 periods (neglecting for the moment all glyphs appearing before the 2nd Rei and all those coming after the last glyph in the 29th period).

By the way, it must be clearly stated that I wrote:

 

Another solution is to count also Rei:

 

		7	see table of high summer below	15
Ka4-15	Ka4-16				*Kb2-14	*Kb2-15
1	2				52	53

Kb1-6 is no longer needeed in the table, because the middle of the 27 glyphs for high summer now is just a single glyph, Kb1-7, with 13 glyphs at left and 13 at right.

From Ka4-15 to high summer = 9 glyphs, high summer = 27 glyphs, from high summer to (but not including) *Kb2-15 = 16 glyphs. Total = 4 * 9 + 4 * 4 = 52:

 

In the middle of the 52 glyphs we have the pair Kb1-10--11, and the other candidates for centre are located earlier:

 

Depending on whether we count from Ka4-15 (blue ordinal numbers) or from the beginning of high summer (Ka5-8, red ordinal numbers), the difference is 10. 10 is also the difference between Kb1-10 and Ka5-14.

Kb1-7 is at the centre of high summer while the centre of summer is the pair Kb1-10--11. From December 21 to Januari 1 there is more than 1 week - 3 glyphs from Kb1-7 to Kb1-10 is about the right distance (if 2 glyphs = 1 week).

Why is Ka5-14 at a centre? Because it is the last glyph on side a. The first side (a) is presumably referring to the 1st half of the year, with side b describing the 2nd half of the year, therefore Ka5-14 will be in the centre of the calendar, too.

There are 97 glyphs on side a and 95 on side b, together 192 glyphs. The centre is therefore the last two glyphs on side a:

 

The most obvious centre is located here. You don't have to know anything about the meaning of the glyphs.

Knowing what a Rei glyph means, you will draw the conclusion that Ka5-13-15 describes a time without a ruler. Affirmation of the chaotic state is shown by the headless glyphs at left. At right, though, from Kb1-2 onwards, a new season with a new ruler will emerge:

 

Notable is the oblique upper end of henua in Kb1-3, the opposite of the oblique bottom end of henua in Kb4-14 (the last glyph in the last period):

 

The bottom oblique end agrees with that in Ab8-83 (the next to last glyph on side b of Tahua).

The distance in glyphs between the oblique henua is 68 glyphs, with 54 of them arriving before line b4. Probably the idea is to count to viri, though:

 

The reversed bent henua in Kb4-5 announces - we can also see by ordinal number 59 - 'the end'. Beyond that, from viri, there remain two periods (28-29) and 9 glyphs (a 'black' number).

The 4 glyphs in period 28 could allude to 364 - 360 and the 5 in period 29 to 365 - 360.

Counting the total number of glyphs in the calendar - from the 2nd Rei (Ka3-15) to the last glyph (Kb4-14) - we reach 107, not a very stimulating number. 59 for the glyphs before the calendar, on the other hand, seems to be a reasonable number:
