Zonal Overview 2013 3.x & 4.x

It didn't take much work to research the question from Zonal Overview 2013 2.x, and it will take even less work for the Asian (3.x) and African (4.x) continents, shown below.

The change in 3.x numbering from C21 to C22 is explained on my page Zonals : Links (and Other References). A special analysis is needed for Africa. Although the overview looks consistent, much of the data for zones 4.1, 4.2, and 4.3 is missing. The current data is filled with placeholders.
