Doppler residuals are the differences between the calculated and
observed. When they are converted to gforce acceleration the
Pioneer anomalous curve is the result. My curve is near enough
to a perfect match and it was generated by the gforce residuals
resulting from the difference between calculations according to
current theory and according to observation, which is according
to my theory. ...

Nope. Changing the speed of light does not result in the Pioneer anomaly. The range to the spacecraft changes by day (due to earth rotation) and by season (due to the earth revolving around the sun). By changing the speed of light, the round trip light time is altered on a daily and seasonal basis. It is not compatible with the Doppler data.
