Yes, these are the kinds of questions for which I haven't found logically derived, or even emperically gathered and statistically valid, answers.

 I don't have this for other models either, but I don't claim to (yet ;-) Relational theorists, writers, or marketers seemed to have snowed even very intelligent people into thinking there is something mathematically, logically, or otherwise superior to any other models, past or even future (at least some have suggested that). In order to move forward, it would be good to relieve ourselves of thinking that relational theory has been anointed by the heavens. It is just one mathematical metaphor (aka model) for data. <end of sermon, back to questions>
