We can now update our table of kuhane stations. Our question has been (tentatively) answered: The 57 glyphs arriving before the glyph with ordinal number equal to a multiple of 59 (counted from Ab8-44) belong to that kuhane station (plus one glyph beyond):

Te Pei 8 * 29.5 = 236		53
	Aa5-41 (415)		Aa6-12	Aa6-13	Aa6-14	Aa6-15 (472)	Aa6-16 (473)
Te Pou 9 * 29.5 = 265.5		53
	Aa6-17 (474)		Aa6-70	Aa6-71	Aa6-72	Aa6-73 (531)	Aa6-74 (532)
Hua Reva 10 * 29.5 = 295		53
	Aa6-75 (533)		Aa7-46	Aa7-47	Aa7-48	Aa7-49 (590)	Aa7-50 (591)
Akahanga 11 * 29.5 = 324.5		53
	Aa7-51 (592)		Aa8-20	Aa8-21	Aa8-22	Aa8-23 (649)	Aa8-24 (650)
Hatinga Te Kohe 12 * 29.5 = 354		53
	Aa8-25 (651)		Aa8-79	Aa8-80	Aa8-81	Aa8-82 (708)	Aa8-83

Here are 295 glyphs = 5 kuhane stations from Aa5-41 up to and including Aa8-83. These 5 stations belong together in A. It remains to be investigated whether there also is a continuity before and after.
