If you use 'just intonation' harmonic ratios (ratii ?) to determine the 'proper' pitch, then you also need to be aware that the pitch for each note is dependent on the 'root' note of the scale being considered.
The proper pitches for the notes of a just intonation scale beginning on concert F (horn C) will be different than the same note names for a scale beginning on concert C (horn G) - even if the horn's A is kept the same. And there will be similar differences for all of the root notes. For general intonation, being able to play all the scales so they sound good is a reasonable goal! This problem with 'moving pitches' is why it is so important to listen carefully when playing in an emsemble and to play your notes so they blend with the others. For me, it is the horn A's and E's that give the most trouble.
