OK, since you insist, one more time:

SWR = (1 + |r|)/(1 - |r|)

Where r = reflection coefficient.

r = (Zl - Zo)/(Zl + Zo)

Where Zl = complex load impedance and Zo = complex source impedance.

And once more time, the formula linking VSWR to Reflection coefficient
uses ONLY the MAGNITUDE of the Reflection Coefficient |r|, taking the
magnitude removes the phase component.

The magnitude DEPENDS on the phase component.

Secondly the formula linking VSWR to Reflection Coefficient is NOT a
definition of VSWR, it is merely a formula that links 2 related
quantities.

So is power P=EI or P=E^2/R?

Which is the "official" definition?
