We use a pseudoscalar correlator calculated from Perturbative QCD up to five loops and use the QCD Finite Energy Sum Rules with integration kernels tuned to suppress the importance of the hadronic resonances. This leads to a substantial reduction in the systematic uncertainties from the experimentally unknown resonance spectral function. We use the method of Fixed Order and Fixed Renormalization Scale Perturbation Theory to compute the integrals.
