Thanks for expanding my vocabulary (hmm, how am I going to use that word in context today?). So, if 5 is the case, then Pat's original statement can be reworded as: "If you pick the possibly too small route, then increasing the size in largish Chinese sailing vessels is much better than adding a row boat at a time." While that is probably true, I am not sure what that would mean in terms of the original data processing question. -- Gregory (Greg) L.
