@ssdecontrol The more I ponder your question the more it seems to be a really good question to ask about (for example, I think it speaks to something many people carry in their heads but don't generally articulate). I hope it gets more attention.
I posted following question this morning on Stackoverflow: stackoverflow.com/questions/28154321/… very low viewership and no answer yet. Wondering if I should switch the question to crossvalidate? any recommendation on that?
