Sure did.

These are

a

I don't have to worry about it. E= M-e.sin(E). I don't need to use
force.
My ellipses are centred at (0,0), have a fixed 1,000,000 pts, fill an
array
of 1000 to fit the screen, I could easily go to 100,000,000 pts if I
wanted too, yours is only fast because you have a paltry 70k pts and
you can't get the eccentricity as high as I can. I've got V1493Aql, you
do not, It's my Rolls-Royce against your Ford, no contest.

Not me. I don't have to worry about an angle being zero.
E = M-e.sin(E)

at 0,
0 = 0 - e.sin(0) = 0
at pi,
pi = pi - e.sin(pi) = pi - 0 = pi

Right on the money!
