Wrong. Newtonian mechanics works quite well on Earth (done any experiments in a lab lately that show otherwise?) and in the Solar System. Only in the case of Mercury is the need for Einstein's amendment strongly needed; and the remaining flyby and Pioneer anomalies are both quite small.

A non sequitur if I ever saw one. Even granting the premise (which I do not) the consequent just does not follow from it.

How about trying some other curves? Exponentials, third-degree polynomials, etc. Bet some of them will fit as well. What justification do you have for the one that you actually chose?

Which sounds impressive (ooh! 111% ooh!) but really is not. A uniform sphere has a moment of inertia of 0.4; a real body will be less because more of the mass is concentrated in a core.

Given your faulty argument starting with albedo, I must find your reasoning about the flyby data equally suspect.
