Quantities representing measurables in physics should not depend on the method of calculating them in the underlying QFT. However, in perturbative QCD, computations must be truncated to a finite order meaning they are only approximations of the true quantity resulting in dependence on the renormalization scheme chosen. We investigate this dependence for the Bjorken sum rule and Adler D functions in various kinematic schemes with particular focus on the symmetric MOM schemes at four loops and compare with MSbar scheme behaviour as the benchmark.
