For the record, these 10 Rogo glyphs are all that I can find in H:

Only Hb11-7 has the peculiar right 'wing' sign we recognize from C:

Hb11-7 has ordinal number 551 (= 19 * 29) counted from Hb1-1. If we add 648 (side a), the sum becomes 551 + 648 = 1199 (= 11 * 109). From Ha1-4 it will be 1199 - 3 = 1196 = 100 less than 1296. From Friday (Hb9-48) its glyph number will be 192 + 1196 = 1388 (= 92 + 1296).

The proper way to measure seems to be from Ha1-1 and divide by 3:

Hb10-64	Hb10-65	Hb10-66	Hb10-67	Hb11-1	Hb11-2
day 397			day 398
Hb11-3	Hb11-4	Hb11-5	Hb11-6	Hb11-7	Hb11-8 (1200)
day 399			day 400
Hb11-9	Hb11-10	Hb11-11	Hb11-12	Hb11-13	Hb11-14
day 401			day 402

Hb11-9 is the same type of glyph which appears e.g. at Ga7-21 and Ga7-30:

Ga7-18	Ga7-19	Ga7-20	Ga7-21 (191)	Ga7-22	Ga7-23	Ga7-24

Ga7-25	Ga7-26	Ga7-27	Ga7-28	Ga7-29	Ga7-30 (200)	Ga7-31

Koti at Hb6-39 seems to be connected with some earlier event than winter solstice. An event which arrives ca 400 - 314 = 86 days (a quarter) earlier should be autumn equinox:

Hb6-35	Hb6-36	Hb6-37	Hb6-38	Hb6-39 (941)	Hb6-40
313			942 / 3 = 314
Hb6-41	Hb6-42	Hb6-43	Hb6-44	Hb6-45	Hb6-46
315			316

Once again, we started out from Friday:

	940			352
Hb9-48 (1)		Hb3-6 (942)	Hb3-7		Hb9-47 (1296)
942 = 3 * 314			354 = 12 * 29.5

If we instead count from Ha1-1, the ordinal number for Hb3-6 will be 753 (equal to day 251, a prime number). Order is established by adding 64 days to 250 in order to reach koti at 314, and day 251 will instead connect to Rogo:

			192
Hb3-4	Hb3-5	Hb3-6 (753)		Hb6-44	Hb6-45	Hb6-46 (948)
251			64	316
66

The 'mock king' comes later:

	232
Hb3-7 (1)		Hb7-31	Hb7-32	Hb7-33
236 = 8 * 29.5

Counted from Ha1-1 he will be glyph number 988, the first glyph in day 330.

			39
b6-44	Hb6-45	Hb6-46 (948)		Hb7-32	Hb7-33	Hb7-34 (990)
day 316			13	day 330

Looking again at the group of 10 Rogo glyphs, we still have not defined the roles of e.g. Hb9-1. Day numbers are inserted:

Hb9-1 is glyph number 1061 counted from Ha1-1, in the center of day 354, with Hb8-51 close by:

*Hb8-51 (1057)	*Hb8-52	*Hb8-53	*Hb8-54	Hb9-1	Hb9-2 (1062)
353			354

Maybe they form a pair in order to put focus on the moon. They mark the end of 12 lunar months.

Hb8-29 has ordinal number 1035 counted from Ha1-1, equal to the end of day 345 (= 15 * 23).
