Counting glyphs from Ca1-1 gives interesting results. 157 = half 314 and 164 can be read as 16 * 4 = 64:

1
Ca6-17 (157) Ca6-18 Ca6-19 Ca6-20 Ca6-21
Ca6-22 Ca6-23 Ca6-24 (164)

64 is the number of days from winter solstice to the beginning of side a in G.

6 * 24 = 31 * 8 = 248. If we expand this number to a year, it will be 31 * 12 = 372. Ca6-24 does not have to be at the midpoint of the calendar, it can be (like the inverted maro in Gb1-7) at the 8th station.

A more slender vero than the Rogo ones is located at day 372, and the glyphs inform us that the end comes with *Ca14-14, with day 377 (= 13 * 29):

glyph numbers are counted from Ca1-1
Ca13-19 (362) Ca13-20 *Ca14-1 *Ca14-2 *Ca14-3
*Ca14-4 *Ca14-5 *Ca14-6 *Ca14-7 *Ca14-8
*Ca14-9 (372) *Ca14-10 *Ca14-11 *Ca14-12 *Ca14-13 *Ca14-14
*Ca14-15 (378) *Ca14-16 *Ca14-17
353 354 355

Because with glyph number 378 a new sequence is beginning, and we will return to Hatinga Te Kohe at 12 * 29.5 = 354. The new sequence jumps back 25 days in time because the days are here counted from Ca1-26:

25 49 312
Ca1-26 Ca3-25 (76) Ca14-26 (389)
50 314
364 = 14 * 26
