If you count the labels on the zodiac folios, you get 29 for March, 15 for April 1 and 2 (so 30 for the month), 15 for May 1 and 2 (so again 30), 29 for June, 30 for July, 30 for August, 30 for September, October, November and December. Could these be days? or "zodiac" coordinates?
Interestingly, march is the only one with a "label" star in the central circle, which adds up to 30. And in the June zodiac there is a figure in the outer circle with no label, the only case in the Zodiac folios. Perhaps the scribe forgot to add a label to that one
Which would make all zodiacs have 30 labels. And each zodiac sign is 30 degrees, so arguably it would make sense for each label to be a degree.
