Barry,
When the CTs become involved the cord structure changes affecting the overtones. A hard mix, where there is long closed phase done via intrinsic musculature, will still have a slightly different tonal quality than chest. If it sound like pure chest above (bflat 4 or so) are the vowels start to get splatty, and laryngeal elevation is evident (as in Dion's Titanic song at the end), it is pulled chest and the increase in pitch is most likely being accomplished via pressed phonation where the mucosa is abnormally stiff in order to accomodate higher pitches. This is part of the reason she can't make a connected line past a certain point and flips off into something resembling falsetto. However, if you are indeed talking about a hard mix as being belt, then you talking about a mix and that should not require laryngeal elevation.
You can document and explain any behavior, but that does not make it healthy. I could document Kerry Woods pre-surgery pitching motion where he can across his body to gain more speed on his pitches and explain it as his technique yet we all know where it led him... brilliant short term success and then to a surgeon.
I know what you'll say... by who's definition? It's starting to sound like Clinton asking someone to define the word is. The fact that you would ask students to only belt occasionally makes me suspect that even you think it is hard on the voice. Why even go there when you can serve the purposes of the music without resorting to this.
