Totally agree with @valued-customer. This is what drives great discussions and learning. Every post that @paulag presents I learn from ... That often includes the great comments. Willingness to change one's mind, given the data, is the mark of a good scientist.
Great post @paulag, I was actually contemplating some of these quandaries as I delegated some SP around. Timely post... Is there a global conciseness ;-)
thank you @jasonbu
