I'm not arguing against your point, but Sokaku Takeda gave kyoju dairi certification to some thirty people - so it wasn't all that rare after all.
Even with thirty, if you know anything about Daito ryu, it's certainly not a K Mart blue light special. Sokaku Takeda's enrollment books show he taught about thirty thousand people. I don't know how you do your math but in the world I live in, that's rare enough!
