Glyph number 300 at Aa8-84 does not imply that it is also day number 300. Instead much evidence suggest we should count with 2 glyphs per day:

296
Ab5-41 (365) Ab5-42 Ab8-83 Ab8-84 (664)
1 2 299 300
1 148 150
60
Aa1-1 Aa1-2 Aa1-64 Aa1-64
301 302 363 364
151 30 182
Aa1-65 Aa1-66 Aa1-67 Aa1-68
365 366 367 368
183 184

The closed mouth vaha mea at Aa1-68 indeed can be read as a combination with puo - the light is gone. Because it is located at the end of the year and it is day number 366, it seems:

360
Ab1-1 (1) Ab1-2 Ab5-39 Ab5-40 (364)
1 180 182
296
Ab5-41 (365) Ab5-42 Ab8-83 Ab8-84 (664)
1 2 299 300
183 148 332
60
Aa1-1 Aa1-2 Aa1-64 Aa1-64
301 302 363 364
333 30 364
Aa1-65 Aa1-66 Aa1-67 Aa1-68
365 366 367 368
365 366

At the beginning of side a the difference between counting 2 glyphs per day from the little viri in Ab1-1 and counting 1 glyph per day from inoino in Ab5-41 has diminished to 32. We can here see 'in action' how two different ways of counting merges at the cardinal point - the end of the year.

Hakaturou in Aa1-64 identifies one of the alternative ends of the year and here the junction is. 364 is the measure.

3 * 64 = 192 and 364 - 192 = 172.

36 * 4 = 144 = 12 * 12 and 364 - 144 = 220.
