We will not go any further in this technical discussion.

But another piece of observation: There are 45 different signs in the Phaistos Disc. (I do not count the two special signs, the 'strings with knots' and a sign looking like /.)

If we divide 360 with 2, 3 or 4 we reach the whole numbers 180, 120 and 90. We can also divide with 5 and 6 reaching 72 and 60.

7, though, does not work. But with 8 we get 45. I think the Polynesians had reasons to divide the horizon into 8 parts. With 16 - the next natural division - you get 22.5 which is unacceptable. Only whole numbers are natural and understandable.

45 degrees therefore ought to be important enough to be seen somewhere in the rongorongo texts. Which means that we should look for 45 days in the yearly calendar. Days and degrees are equivalent if you disregard periods shorter than what corresponds to division with 8.
