In this context, we perform fits of the strong coupling constant for the soft-drop thrust distribution at NLO+NLL accuracy to pseudo data generated by the \\textsf{Sherpa}~event generator. In particular, we focus on the impact of hadronisation corrections, which we estimate both with an analytical model and a Monte-Carlo based one, on the fitted value of $\\alpha_s(m_Z)$. We find that grooming can reduce the size of the shift in the fitted value of $\\alpha_s$ due to hadronisation.
