In the G calendar for the year there is only one GD16 glyph, located in the 17th period (the first of the two autumn equinox periods):

17 Ga5-4 Ga5-5 Ga5-6 Ga5-7 Ga5-8 Ga5-9 18 Ga5-10 Ga5-11 Ga5-12 Ga5-13 Ga5-14 Ga5-15 Ga5-16

Maybe the running person in Ga5-7 is meant to illustrate how the sun is moving north?
