So, the area over time on any segment of the ellipsoid is the same.

And the time of the orbit is roughly the same whether circular or elliptical, given a fixed input of impulse.

I think I have that. Thank you.

The period of an orbit with semimajor axis r is exactly the same as a circular orbit with radius r. I was pointing out that for low eccentricity, the path length of the elliptical orbit is very close to that of the circular orbit, so the average speed is nearly the same, being nearly the same distance divided by exactly the same time.
