  The Karsten-Wilczek action is a formulation of minimally doubled fermions on
the lattice. It explicitly breaks hypercubic symmetry and introduces three
counterterms with respective bare parameters. We present a tuning of the bare
parameters of the Karsten-Wilczek action on staggered configurations at the
physical point. We study the magnitude of the taste-splitting as a function of
the lattice spacing.
