  Prompted by recent measurements, we have surveyed world data and calculated
radiative and isospin-symmetry breaking corrections for the superallowed 0+
-to- 0+ Fermi transitions from 42Ti, 46Cr, 50Fe and 54Ni. This increases the
number of such transition with a complete set of calculated corrections from 20
to 23. The results are compared with their equivalents for the mirror
superallowed transitions from 42Sc, 46V, 50Mn and 54Co. The predicted ft-value
asymmetries of these mirror pairs are sensitive to the correction terms and
provide motivation for improving measurement precision so as to be able to test
the corrections. To aid in that endeavor, we present a parameterization for
calculating the f values for the new transitions to plus/minus 0.01%.
