Yes, and if the orbit were LONGER (days from one perihelion to another)
during that year, then the sum of the days between full moons or
equinoxes would likewise be LONGER, right?  I'm picturing a couple,
twirling on the dance floor.  If they are moving down the dance floor
away from me, it will take longer for the woman's face to appear full as
they are covering more distance while moving away. But if they are
twirling toward and past me, then her face would appear full at a
relatively faster rate.  Is this correct?  The full moon would take
LONGER during that part of the orbit when the Earth is pulling away from
the Sun in it's not-quite-circular orbit, right?
