More correctly, it's that both craft seem to lose velocity in time
along their velocity line, regardless of direction. Your version
implies that the sun has something to do with it which is not a
"given".

"Velocity line"? Why not say speed if it's "regardless of direction"? Velocity doesn't just have more syllables, it has the added meaning of direction. It's a vector. And the sun has everything to do with it - the Pioneers are being decelerated by the Sun's gravity and by something else. The measured deceleration is toward the Sun - strictly, line of sight to the Earth but the two cannot be distinguished. Motion at right angles to line of sight is apparently not as well known, which may provide food for thought.



As to the planet neutrality, I am harboring the idea that the satellite is a "Nova" launched by man from Earth and thus might act differently from the solar system which was initially launched at creation 11 Byrs ago.

More nonsense - and this time it wouldn't even make a Star Trek script. BTW, the accepted figure is now 13.7 billion for the universe, 4.5 billion for the solar system.


Bear in mind, we are not sending 2-way signals
to the moon or mars and studying their possible Doppler drifts, and
that is all we have to study withr the Pioneer.

Actually we are. If you read Anderson et al. "Study of the anomalous acceleration of Pioneer 10 and 11" you will find that Viking data exists and rules out a "Pioneer effect" for Mars.
