We present a general procedure for applying the scale-setting prescription
of Brodsky, Lepage and Mackenzie to higher orders in the strong coupling co
nstant as. In particular, rye show how to apply this prescription when the
leading coefficient or coefficients in a series in a, are anomalously small
. We give a general method for computing an optimum scale numerically, with
in dimensional regularization, and in cases when the coefficients of a seri
es are known. We find significant corrections to the scales for Re+e-, Gamm
a (B --> X(u)e<(<nu>)over bar>), Gamma (t --> bW), and the ratios of the qu
ark pole to (MS) over bar and lattice bare masses.
