Thank you very much to adding this detail, as it alleviates much of my concern - specifically regarding Cook's response to a derivative question (which would be much more "dangerous" to respond to without fear of conflict).  Cook did the right thing IMO considering the clarified circumstance. I for one am clueless as to Ward's intent with that follow-up question (i.e., it either makes no sense or my ignorance prevails - probably the latter!).  Limiting factor?  When smoke pours out of the box! LOL

Thank you, thank you, thank you!

Any thoughts/clarification on the "groupedness" thing?  Do I have the context correct (multiple fetch)?
