   I'm unsure which deity to invoke, Maxwell, i think.

   Guaranteed some charge, substantial will remain.
   Some will be lost, then they will 'equalize', at
   lower voltage/charge.

   I'm not gonna tackle the math, a good circuit simulator,
   or even a test rig would be interesting/instructive.

   No DC path from the 'inner' caps, round the loop,
   to equalize.
