  We explore the relationship between the DRED and NSVZ schemes. Using certain
exact results for the soft scalar mass $\beta$-function, we derive the
transformation of $\alpha^{\DRED}$ to $\alpha^{\NSVZ}$ through terms of order
$\alpha^4$. We thus incidentally determine $\beta_{\alpha}^{\DRED}$ through
four loops, and we compare our result to a previous Pad\'e Approximant
prediction.
