The symmetric momentum subtraction scheme (SMOM) has been introduced to overcome exceptional momentum flows. However, it is quite restrictive to the momentum choice - the momentum squared of all legs are identical. Therefore, a generalization called interpolating momentum subtraction scheme (IMOM) has been developed, where a free parameter $\omega$ allows for more freedom in the momentum assignment. Especially, on lattices this is of great importance. We investigate the IMOM scheme for local operators for small coupling and compare with results obtained in continuum 2-loop perturbation theory. The implications for larger couplings are discussed.
