Yup, and to further muddy things, the letter system
was based on diametre of *silk* lines, so any conversion
to the modern system is at *best* an approximation. :-)

From what I know of 'boo rods, there's a fair bit of
leeway as far as which line size works best for *you*.
Indeed, I've seen people disagree +/- a line wt. w.r.t.
the line *they* thought worked best. The conversion
gives you a ballpark number, but you pretty well *have*
to experiment a bit to see what really suits the rod.
