Looking for more dots in G it did not take long before I also saw the one in period 10 (cfr above). Both cases are characterized by being located in the last glyph before a redmarked period is beginning. Could it be something else than chance? The question can only be answered by listing all glyphs with such dots:

Ga1-7 (8)	Ga1-16 (17)	Ga1-20 (21)	Ga1-21 (22)	Ga1-24 (25)	Ga4-10 (94)
Ga4-22 (106)	Ga4-23 (107)	Ga4-24 (108)	Ga4-25 (109)	Ga5-18 (129)	Ga6-4 (145)
Ga6-15 (156)	Ga7-2 (172)	Ga7-7 (177)	Ga8-22 (226)	Ga8-25 (229)
Gb1-13 (243)	Gb1-23 (253)	Gb1-24 (254)	Gb2-3 (259)	Gb2-5 (261)	Gb2-6 (262)
Gb2-7 (263)	Gb3-3 (294)	Gb3-26 (317)	Gb3-27 (318)	Gb4-11 (332)	Gb4-12 (333)
Gb4-29 (350)	Gb4-31 (352)	Gb5-3 (357)	Gb8-3 (465)	Gb8-20 (462)	Gb8-27 (469)
Gb8-28 (470)

Ka2-4 (28)	Ka2-7 (31)	Ka2-8 (32)	Ka2-19 (43)
Ka3-7 (53)	Ka4-6 (73)	Ka4-7 (74)
Kb1-8 (105)	Kb1-13 (110)	Kb4-12 (165)	Kb4-14 (167)
Kb4-18 (171)

I found 36 dots in G and 12 in K. I have redmarked a few which obviously are meant to be noticed by the reader. The dots are signs. On all four sides the number of dots are odd (17 + 19 = 36 respectively 7 + 5 = 12). But I may have missed some dot or mistakenly seen a dot where there is none.
