I too found it difficult drawing ellipses, and truth be told I still struggle with them sometimes (from time to time I get weird muscles spasms while I draw them)
Anyway I think it is just a matter of practice and time to be honest.
However I did try in the past months methods to make them better, but the results were not always satisfactory, one thing I did was to not ghost too much, like for maximum 4 to 6 times.
I also tried the reverse like ghosting from 10 to over 10 times, I think I got better results with the first method .
One other thing I did (and still do during awful drawing days) is to draw big ellipses with out any kind of confinements, I feel like it makes me use my shoulder to the fullest and also kinda helps me notice later on if I'm using my arm instead of my shoulder while drawing.
I hope these tips can help, however ultimately I think it just depends on practice.
