I must be stupid; with 2 hex chars (dir structure like 0a/7b/...) wouldn't we have 16*16 = 256 (edit: can't do math) entries per directory, not 96?

256 actually, but I have no idea where that 96 comes from, it was probably the alcohol typing (or I was already thinking 4096 and I wrote part of that instead of the correct number)

Worth mentioning that's "directory entries per directory". The "data files per directory" isn't driven by the intermediate path...just the total number of "full paths".
