The anomalous acceleration for Pioneer occurred also for four total
satellites / probes.  The anomalous acceleration was "sudden onset",
and occured at different distances from the Sun.

It is wrong for Big Bang expansion as the cause, yes.  Your "math"
returns results that simply modify local G, which *still* fails to
describe the pioneer anomaly.

These links probably will give you what you seek:
