In H a pair of tagata maitaki have rhombic heads, whereas in P they are circular. One of them (Pb11-26) has no inside vertical line (cfr Hb1-3), which certainly is a Sign. 112 * 6 = 672 = 3 * 224 and 112 * 4 = 448 = 2 * 224..

Niu in Hb10-23 is glyph 1149, presumably to identify its position as day 13 * 29½ (because 1149 / 3 = 383). In G we found this day could be correlated with February 23:
... The ordinary year in the previous Roman calendar consisted of 12 months, for a total of 355 days. In addition, a 27-day intercalary month, the Mensis Intercalaris, was sometimes inserted between February and March. This intercalary month was formed by inserting 22 days after the first 23 or 24 days of February; the last five days of February, which counted down toward the start of March, became the last five days of Intercalaris. The net effect was to add 22 or 23 days to the year, forming an intercalary year of 377 or 378 day...

In P the position of niu seems to be day 377 (= 1131 / 3). According to G the date February 17 is the day before hakaariki (making a King). Position 377 is the day before the end of Saturn's synodic cycle.

Gregorian day number 413 (P) identifies the last part of a 'great fortnight', because 14 * 29½ = 413.
In H the final arrives 6 nights later, because its niu coincides with the break between the last glyph in line Gb5 and the first in line Gb6, which evidently is based on the same structure as was used in the old Roman calendar. Also here the lunar synodic cycle (29½ nights) is used, however with 13 * 29½ = 383½ as the limit.
Castor passed overhead at midnight in February 23. What star passed overhead at midnight 6 days earlier? At the time of my astronomy book Castor's heliacal rising occurred 114 days after March 21, i.e. in July 13. However, if reduced with 1 day due to the effects of precession it ought to have been in July 12. The answer to my question is Wezen which rose heliacally at 7h:
