We develop optimized approaches for the evaluation of curvature and gravitational wave power spectra from single field inflation using the generalized slow-roll approach to extend the validity of the standard slow-roll approximation. Since the deviations from scale-invariance are only assumed to be small in amplitude not in temporal frequency, our approach applies to models with features in the potential.
