Professor Tim Beers has indeed presented a very up-to-date account of existing statistical tests for the assessment of subclustering in clusters of galaxies, with due emphasis on their limitations due to astronomical as well as statistical constraints. Although I endorse his views to a greater extent, I have a few dissenting comments to offer, and I shall mostly confine myself to them.
