In December Danny Sprung posted a draft "Regional"-level convention chart for comments in this thread.
There is now an updated version at https://docs.google.com/document/d/1I0Gy68AKZq8aODBRgp3NoemKdRF2oQXcY4czoUwU7II/edit#heading=h.tx8hwzaghlm4
We would appreciate further comments.

Thanks to the BW community for their help with this.
Plus... it's free!
