The nstep=0 output is always instantaneous.  Throw that away in the
average and you should get the right answer so long as the fields are
themselves averaged.  To illustrate what I mean, try writing the model
timestep to the history files, e.g.:

fincl1 = 'NSTEP:A'
fincl2 = 'NSTEP:A'

I tried this and got the right answer.

Hope this clears up the discrepancy.
