  We compare the logarithmic Sudakov expansions of the process e+e- --> W+W- in
the one-loop approximation and in the resummed version, to subleading order
accuracy, in the SM case and in a light SUSY scenario for the MSSM. We show
that the two expansions are essentially identical below 1 TeV, but differ
drastically at higher (2,3 TeV) center of mass energies. Starting from these
conclusions, we argue that a complete one-loop calculation in the energy region
below 1 TeV does not seem to need extra two-loop corrections, in spite of the
relatively large size of the one-loop effects.
