Agree fully, but on the first point I would add

that it's fine for people like us to ponder how many national championships ND would have if "Alabama math" or "Michigan arithmetic" were used.

ND only claims the 11 titles that are truly consensus championships: 1924, 1929, 1930, 1943, 1946, 1947, 1949, 1966, 1973, 1977, and 1988. Fair enough. But under the expansive definitions used by most other schools, we'd add at least the following seven:

1919*
1920
1953**
1964*
1970
1989
1993

* -- recognized by College Football Data Warehouse
** -- recognized by most ranking systems that year except AP and UPI
