That still sounds like you're confused about it.

If you normalise the master output, it does not affect your mixing
balance at all. All the mysterious "mathematical function" does is:
1. play the song through a "peak hold" meter.
2. look at the maximum peak level, say it's minus n dB FS.
3. play the song again with the master fader at plus n dB FS
4. save the result

If by "tracks", you actually mean "songs", well then, yes, if you have
one song per session, normalizing each one individually can upset the
loudness balance from one song to the next, but I doubt you'd get that
one perfect anyway. For this kind of workflow, when switching songs
then create a new ardour session with as many stereo tracks as your
album has songs, arrange the songs one after another, but each on an
individual track. Then you can fine-tune the relative levels with the
channel faders and even throw in some extra "mastering" processing like
EQ if the songs don't quite match yet.

All best,

Jörn
