Not very scientific but common mode circuits are elusive to understand and simulate.

Not true. I've done a lot of research on common mode chokes and published the results, first in 2005, then in 2008, updated in 2010 and 2016, and most recently in 2018. Once you understand the equivalent circuit of a ferrite choke, you can analyze it in the common mode circuit.

Beginning on page 41 of RFI-Ham, I related my interface with engineers from CIA, the leader of which subsequently forwarded me an unclassified 1966 DOD study that came to all of the same conclusions I did.
