Vaha kai in *Qa7-16 seems to identify a day similar to day 364, a day where 'sun is swallowed' (here the sun of spring). Also in the text of G day number 192 and 200 are located in glyph line a7:

 

Ga7-18	Ga7-19	Ga7-20	Ga7-21	Ga7-22 (192)
Ga7-23	Ga7-24	Ga7-25	Ga7-26	Ga7-27
Ga7-28	Ga7-29	Ga7-30 (200)	Ga7-31	Ga7-32

Remarkably, if we add 64 to 192 (in order to measure the number of days from Rogo at winter solstice) the result is 256, the ordinal number for *Qa7-2 counted from Qa1-1.

256 / 2 + 64 = 192, and 192 + 64 = 256. This paradox can be solved by reflecting on the facts. 4 * 64 = 256, and 192 = 3 * 64.
