We examine current intermediate-energy nucleon-nucleon data sensitive to T asymmetry and conclude that of these data, some np polarization and asymmetry measurements give the best evidence that T is good, despite the fact that these data have the largest errors of any of the data considered. This conclusion is reached using a one-boson-exchange potential due to Bryan and Gersten, wherein T is violated at short distances. We argue that any short-range T-asymmetric model would probably lead to the same conculsion. We show that the current N-N data admit the possibility of strong-interaction T asymmetry, so long as it be of short range. For experimentalists who may search for strong-interaction T violation in intermediate energy N-N scattering, we suggest maximum errors for several measurements so that any such T violation may not be missed.
