A high precision calculation of the event shape DIS thrust, with next-to-next-to-next-to-leadinglogarithmic resummation and a rigorous treatment of hadronization corrections, is presented.Perturbative resummation uncertainties in the cross section are reduced to the 2% level for a significant region of the HERA phase space in x and Q, thus allowing for new accurate measurements of α s (m Z ).
