George, your whole argument is based on the shapiro delay
peak being 90 out of phase from the velocity peak.

You haven't calculated the velocity curve yet so we don't
know when the velocity peaks occur, so there is no way to
know the relationships between them and the Shapiro delay
peak. We know that the Shapiro delay peak must be when the
pulsar is at superior conjunction. You have to tell us
where the velocity peaks occur and what their relationship
is to the Shapiro peak.
