Feedback loop of Flyback SMPS with load at end of long cable?

On a similar note....
Supposing a 150W DCM flyback has a 4mF “local” output capacitor, (C1) then at the end of a cable of resistance 0.5R, (Rs), has the 150W load (RL) and a 22mF output capacitor (C2)

C1 has ESR of Re Ohms

…So, would the power stage poles and zeros be as follows…

Load pole = 1/(C1.(RL+Rs) )
Output cap zero = 1/(Re.C1)
Output pole = 1/(Rs.C2)

…Is that all?.....any more zeros and poles?
