Abstract
Recently it was suggested that the observation of superluminal neutrinos by the OPERA collaboration may be due to group velocity effects resulting from close-to-maximal oscillation between neutrino mass eigenstates, in analogy to known effects in optics. We show that superluminal propagation does occur through this effect for a series of very narrow energy ranges, but this phenomenum cannot explain the OPERA measurement.

Reworking includes corrections due to finite width of the wave packet, further references, and comments on other corrections, causality, the new OPERA results, and why the size of neutrino wave packet provides important constraints
