If we see it from the STRICT Tuners point of view, that's right, and I enter between "the most tuning enthusiasts" (Please Gary put me into the list :-) ). Yes !!! this is the matter I have worked in my free-time for no less than 30 years. There are also others points of view. - The 12 semitonic intervals are closed in 13 notes. This happens in the note-book. - In the piano, the white keys per Octave are 8. - In the staff, in any key, we must count 8 notes to find the note-symbol of a note one Octave appart. > > Ideally fifths would have been called fourths, unisons called zeros, >octaves sevenths, thirds seconds, and so forth.

As a mathematical concept all of this occur from the use of a Ordinal Scale instead of a Scalar Scale. The Ordinal begins with 1 (one) and the Scalar from 0 (zero). Ordinal comes from "orden" that means "order", >If, historically speaking, >we had recognized the (perfect) unison as a pitch difference of zero (which >is after all exactly what it is) then fourths would have been called >thirds, thirds called seconds, and sixths called fifths, and the result >would have been correct: 3+2=5. > It seems there is a happy (or not) coincidence between the zero as a pitch difference and the zero of the Scalar Scale.

The ordinal numbers (distances) such as Fourth, Fifth, Octave, are Ordinals. NOTES are counted. And in the case of 7, 12, 19, INTERVALS (or Chromatic notes) are counted.
