We study in the case of equal photon virtualities the main systematic effects, by considering a different representation of the amplitude and different optimization methods of the perturbative series.4 pages; talk at 15th International Workshop on Deep Inelastic Scattering and Related Subjects (DIS 2007), Munich, Germany, 16-20 Apr 2007High Energy Physics - Phenomenologytext
