I went about roughly the pace that I expected to do, which is quite a bit slower than what I wanted. When I was browsing the Internet yesterday, I noticed that one of my favorite authors commented that while she was writing one of her books, it stayed about three chapters from the end for five chapters.
For the 16th, 17th, and 18th centuries, I was looking up and adding information for that period on four cities each, along with minimal extending of the aids, which just goes to show how far behind where I would like them to be some of them are.
That would have been about the extent of it for the 19th century as well, except that I was able to go a level deeper. The stubs of the 20-year periods (from the late 18th century) through the 19th century are now caught up to where they ought to be at this stage of development. The work I have been doing with developing the histories of nations finally reached into what I call the late 19th century, 1881 to 1900, and I was able to add a little more detail to the histories of the United States, China, India, and Indonesia for this period, although the obnoxious problem of Western bias which gives the Asian nations too little attention surfaced again, as it is likely to continue to do.
The problems I've noted of having too little information or having it in the wrong place aren't quite as easy to fix as I had thought, although I got it closer to correct when I was working on the late 18th century. I expect I should be able to fix things in the next development cycle, starting with what's left in this one. I'm now clear to work on the 20th century.
