rho = (Z0-Zload)/(Z0+Zload)
SWR = (1+rho)/(1-rho)
Your application of the above equations neglects the first discontinuity.
The first discontinuity (inside the source) doesn't
have any effect on the SWR on the transmission line.
Tuners at the source present another discontinuity
and have no effect on transmission line SWR.
