      abstract     = {When designing lattice actions, gauge field smearing is
                      often used in the definition of the lattice Dirac operator.
                      Too much smearing can result in uncontrolled continuum
                      extrapolations as the short distance behaviour of the theory
                      is mutilated, which is a situation to be avoided. As a
                      smearing prescription we focus on the gradient flow
                      formalism as it allows to study both smearing and physical
                      flow simultaneously. We investigate the effect of smearing
                      and physical flow on the scaling towards the continuum limit
                      in pure gauge theory. We focus on the example of Creutz
                      ratios, which provide a measure of the physical forces felt
                      by the fermions. For suitable smearing strengths we further
                      investigate the impact of replacing the Wilson gradient flow
                      by stout smearing.},
