Do Dresden Serpent numbers hold clues to correlation constant?

The 8 "Serpent Numbers" on pages 61-62 of the Dresden codex are displayed in
four interleaved pairs, counted from a base date 19.16.3.16.14.11.4 9 K'an 12
K'ayab, more than 4 pictuns earlier, to dates in the 9th or 10th baktun.

Four of these, one from each pair (which seems a significant fact) show moon
ages which would be correct for a first appearance of new moon, IF we use the
correlation constant 584283 (not 584285).  Since we do not know that these
dates are supposed to refer to new moons, this is simply an intriguing fact.
Notice that if we use correlation constant 584285, the moon ages will be too
far past new moon for this to be significant (3.3 to 3.8 days for these first
four dates).

(While I have followed the debates on the correlation constant, and believe I
understand them at least mostly, I hope colleagues will forgive me if I am not
an active partisan of either of these two correlation constants.  I am
providing this suggestion regarding the Dresden Serpent Numbers merely as a
curiosity, in the hopes others can make progress with it.)

The calculations four four dates (numbers 1,3,5,7) are:

+4.6.0.13.15.1  ->  9.17.8.8.5  3 Chicchan 18 Xul       Moon age 1.3
+4.6.10.9.10.1  ->  10.7.4.3.5  3 Chicchan 13 Yaxk'in   Moon age 1.3
+4.6.11.10.7.2  ->  10.8.5.0.6  3 Cimi 14 K'ayab        Moon age 1.5
+4.6.1.9.15.0   ->  9.18.4.8.4  3 K'an 17 Uo            Moon age 1.8

The other four (dates 2,4,6,8):

+4.6.14.11.3.1  ->  10.11.5.14.5   3 Chicchan 13 Pax    Moon age 27.8
+4.6.1.11.5.0   ->  9.18.5.16.4    3 K'an 12 Yax        Moon age 19.8
+4.6.7.12.4.10  ->  10.4.6.15.14   3 Ix 7 Pax           Moon age 12.2
+4.6.9.15.12.19 ->  10.6.10.6.3   13 Ak'bal 1 K'ank'in  Moon age 10.0

The first four are also included among the six, the last digit of whose
4-Pictun distance number is 0, 1, or 2 (rather than 10 or 19).  Could this be
an adjustment mechanism for small decimal or fractional values by using large
numbers?

The last two serpent numbers, on Dresden page 69, do not have this property:

9.16.8.5.12     4 Eb 5 Ch'en    Moon 150 degrees ahead of sun
9.17.15.6.14    9 Ix 12 Zip     Moon 120 degrees ahead of sun

Notice that the eighth, ninth, and tenth of these dates are the only ones in
the set of 10 which do not have "3" as the Tzolk'in number, and they all have
Moon ages somewhat short of full moon.

A set of astronomical graphs for these 10 dates, displaying the motion of the
moon and planets on the ecliptic versus time during a twenty-day period
surrounding each of the dates, is available by mail.  (The set also includes
two graphs of the date which has been suggested recently in National Geographic
as the beginning of the Chinese calendar, when "the five planets were lined up
like pearls" in Pegasus, just before new moon the beginning of Spring.)
It can be obtained by sending $1 and either a stick-on address label or a

Other planetary properties of the 10 dates,
    which may or may not be significant, here just for information:
-------
Date 1      Jupiter just past conjunction with the sun,
            Mercury rising as morning star
            Only Saturn far away from sun, around 180 degrees (in retrograde)
Date 3      Mercury around maximum elongation as morning star
            Venus is morning star
Date 5      Mercury beginning to fall as evening star
            Venus and Mars in conjunction as morning stars
Date 7      Mercury around maximum elongation as evening star
            Venus near conjunction with Mercury
-------
Date 2          (Saturn around 145 degrees)
Date 4      Venus in conjunction with sun (to emerge as evening star)
                (Saturn and Mars less than 50 degrees away from sun)
Date 6      Mercury and Venus nearing maxima as morning stars
            Mars near conjunction with Mercury
                (Only Saturn far away from sun, around 260 degrees)
Date 8      Mercury at maximum as morning star
            Venus near maximum as evening star
            Mars and Jupiter within 50 degrees of sun
                (Saturn around 110 degrees away from sun)
-------
Date 9      Mercury emerging from conjunction, as evening star
            Mars and (nearly) Jupiter within 50 degrees of sun
                (Saturn far from sun, around 240 degrees)
Date 10     Both Mercury and Venus in conjunction with sun,
            Mercury to emerge as evening, Venus as morning star
                (Saturn about 40 degrees from sun, Mars 250, Jupiter 270)

Best wishes for your solving some part of this puzzle!
