We can try to redefine 'summer' as 206 days (ca 7 months) ending at Gb3-1:

	92		55		55
Ga4-3		Ga7-10		Gb1-6		Gb3-1
94 ↑			112 →
206

67		111
	Gb5-6		Gb8-30
68		112
180

We immediately note the general similarity in structure between the newly defined 'summer' and the rest of the text on side b: Both end with a sequence of 112 glyphs. It would be an even more balanced picture if we somehow could change 94 to 68.
