We estimate the presently unknown constant in the 4-loop relation between the quark pole mass and the MS mass, by requiring stability of the perturbative prediction for Etot(r) = 2mpole + VQCD(r) in the intermediate-distance region. The estimate is fairly sharp due to a severe cancellation between 2mpole and VQCD(r). This would provide a test, based on general properties of the gauge theory, for the size of ultra-soft contributions to VQCD(r)
