Haha, OK, metaphorical bookends makes both axes being discussed eminently more understandable, at least for me! (Could I be so impudent to ponder if the good professor chose "P"eru as his SA bookend for its alliterative effect?)

Thanks again for the ping to this thread (where we are actually discussing the content of the other thread!), since it has engaged me in the type of thought provoking discussion that I was so fond of at FR in the past. Isee that you have further discussion downthread that I will get to tomorrow. We're settling in for a late dinner soon and some relaxation tonight!

Another “playing for all the marbles” bump. Wake up, folks - it’s now or seriously never.
