Fair point about number of majors. It’s always good to be wary of attaching too much weight to any one statistic. It’s just awfully hard to know how to interpret sparse bits of anecdotal data (“I heard such and such a department is pretty good”) when it’s impractical to visit everywhere and form one’s own opinion. I find myself grasping for something quantitative to pre-filter the vast list of potential candidate schools down to something manageable, and that has its associated perils.
