Zonal Overview 2013 1.x

Continuing with Zonal Overview 2013, I looked into the anomalies shown in the table on that post and added notes for them. The zonal numbering changed to the continental system in the mid-1990s, so the technique I used is only useful through cycle 15.

For cycles 16 and later, I created a similar table for the European continent, i.e. zones numbered 1.x. Not shown in the table are the first continental championships that replaced the zonals starting in cycle 20.

After analyzing these results, I'll tackle the American continent, zones 2.x.
