So why doesn't the calculation method that successfully accounts for Jupiter in the analysis of the orbits of the other planets work for Mercury?

T is for 2pi radians only. (v/c)^2 - delay, light aberration, ect. a = 1.75 arcsecs - deflection angle. 1.75 / 3600 / 360 = (v/c)^2; v = 350 km/s - CMB radiation. v - average star-sun velocity. Shapiro - (v/c)^2; simple Sagnac effect.

T1 = d(t=0)/c, light speed on Mars is c; and back: T2 = d(t=T1)/c; light speed on Earth is c; ====== v = 350 km/s - solar wind speed, not stars.
