Thanks Pete for posting the chart, I for one did not know it existed.
No problem, Dick.
This chart has been kicking around for at least a few years. I'm sure there is an update somewhere but I can't find it. It looks like this document was used by JD for their sales force so I wasn't expecting to see it on the JD website. However, I find it very useful and I was hoping someone here had a newer version.
Happy New Year!
