I'm almost certain that numbers matter, the amount of attention to the tiniest detail is seen through all the MS.
In some sectors he took effort to fit a star very close to the center (e.g. 2 o'clock), while e.g. at 3 o'clock there evidently is room for one more star which is not used though.
At six o'clock, as I wrote above, there are suspicious lines "connecting" small stars to large stars, look like pointers.
Also, through differences in ink intensity, it is seen that the sectors were not filled in simple clockwise (or couterclockwise) fashion. That would be unrealistic if it were a simple filler.
One more thing is that there seems to be some writing here and there under the blue paint, maybe some reminders which are not needed in the finished drawing.
