We observe a significant reduction of the theoretical uncertainty and discuss the sensitivity to the top quark mass and width. %K electron positron: annihilation (autogen) %K quark: pair (autogen) %K top: mass (autogen) %K quantum chromodynamics (autogen) %K pair production (autogen) %K sensitivity (autogen) %K anti-top (autogen) %F PUB:(DE-HGF)25 ; PUB:(DE-HGF)29 %9 PreprintReport %U https://bib-pubdb1.desy.de/record/221051
