I can't be sure, but you may be implying that defending myself from Southern Comfort's repeated insults about me is a petty concern, either for myself or for the moderators or that refusing to expose myself to further insults by him for the sake of requests for discussion of "liturgy matters" by quaeritor is equally petty. I uphold your right to hold such a view if indeed that is your view, but don't expect me to warm to discussion with you if that is indeed your view. You might even like to clarify what you meant by the remarks in your post.
Nazard,
Academia can't suggest a specific rhythmic approach to any specific chant, notation of a chant or genre of chant out of a number of more or less equally academically justifiable interpretations. I know of one academic who (if I remember his drift correctly) considers that the only people who can properly produce any chant interpretations are the most highly skilled of musicologists. This is certainly so with regard to producing performing editions, and one set of academics would produce one performing editions just as valid/invalid as a performing edition produced by another set of academics.
For this reason, I think, there is no manual stating, "this is how to do it". What is actually happening is people are learning how to read the ancient notations. They are buying copies of tomes such as Solesmes' Graduale Triplex (1979) and the International Society for the Study of Gregorian Chant's Graduale Novum I (2011) which contain a staved edition of the melodies plus transcriptions of the ancient documents like Laon 239 and Einsiedeln 121 set above and below the stave. They may then check other ancient documents which have been digitised on the web for the notations there. They then decide how they're going to sing the staved version of their choice.
This is not a very practical position to be in. I was very heartened by the proportionalism I saw in the preface to Solesmes Liber Hymnarius but the following video seems to deny proportionalism in the ancient notations and I haven't yet heard any recordings by Solesmes which suggest otherwise.

So, to understand the argument for proportionalism at its most basic, the most modern volumes you can read on the new approach to Gregorian rhythm are Fr Jan Vollaerts' now quite outdated Rhythmic Proportions in Early Medieval Ecclesiastical Chant and Dom A Gregory Murray's similarly outdated Gregorian Chant According to the Manuscripts. The latter can be sourced online however.

If you're interested in reading a history of the development of theories of Gregorian chant, John Rayburn's Gregorian Chant: A History Of The Controversy Concerning Its Rhythm is a good start and can be sourced online.

It isn't as hard to read rhythms out of these early notations as it might seem. Check out the following webpage for a look at some basic Breton signs.

Here is the web address of my article assessing the most important historal evidence for strict proportionalism (rather than nuanced proportionalism).

Here's my rather rhythmically conservative interpretation of the Pentecost introit, Spiritus Domini, to show you just how differently to Solesmes (and similarly to eastern Mediterranean chant) it is possible to interpret the ancient notation. Click on the image to expand.
