A comparison is made between about 300 recent determinations of the distances to eight nearby galaxies, one group, and three clusters, made by different authors using new and improved methods and the distances adopted previously by proponents of the two competing extragalactic distance scales: the short scale and the long scale. It is found that there is a close agreement between the short-scale moduli and the new estimates at all distances from the Large Magellanic Cloud to the Coma Cluster, with the mean systematic difference Delta-distance modulus (short - others) being only -0.04 +/- 0.02 mag. There is little evidence for a progressive Malmquist bias in the short scale compared with all others over the whole distance modulus (DM) interval (MD between 18 and 35). The arguments still supporting the long scale and detracting from the short scale are reviewed.
