The method I use is to reduce the difference between actual speed and

fixed factor per unit distance.
speed relatively to what ? Ether ?
If you didn't snip MORON, you would see that I plainly stated the
reference for
speed....the binary barycentre..
I'm not talking about emission speed in your so-called 'model'... but
final
speed.
The final speed is c wrt the barycentre. It is c+u wrt Earth where u is
the
speed of the barycentre wrt earth.
Actually it wont be exactly that for other reasons.
It needs to be c/n to explain frequency-dependent
pulse dispersion, and I would presume you would
then say c/n relative to the medium which produces
that refractive index, i.e. the ISM.
Yes it wil be something like c/n...but n is virtually 1 anyway.
