  A model calculation of deuteron electrodisintegration is used to explore
renormalization group (RG) scale dependence for knock-out reactions. When
evolved to different resolutions with the similarity RG (SRG), the initial
deuteron wave function, the current operator, and the final state interactions
(FSI) are all modified, but how they combine depends strongly on the kinematic
region. In some regions, for example, the FSI are largely unaffected by
evolution, while elsewhere FSI are greatly reduced. For certain kinematics, the
impulse approximation at a high RG resolution gives an intuitive picture in
terms of a one-body current breaking up a short-range correlated neutron-proton
pair, although FSI distort this simple picture. With evolution to low
resolution, however, the cross section is unchanged but a very different and
arguably simpler intuitive picture emerges, with the evolved current
efficiently represented at low momentum through derivative expansions or
low-rank singular value decompositions. A consequence is that intuition about
physics such as the role of short-range correlations or $D$-state mixing in
particular kinematic regimes can be strongly scale dependent.
