I've added some simple diagrams to text to try and show that its the other way around; apparent outliers tend to reject themselves because they stubbornly refuse to join a 'line of best fit', but whereas in the past I've been able to place text and diagrams directly here I can't this morning, for reasons unclear.
Therefore the next least-worst alternative has been adopted, and I've attached my reply as a PDF file. Hope you can open it. Its only about 60KB, thus a file of modest size.
