I agree, I like the narrative approach. I especially hope the writer would break the narrative into logical paragraphs (childhood, military, marriage, career, children, etc, death). I have seen several with one long paragraph - hard to read and hard to find any detail.
I agree about the charts in the bio. They break up the flow of the biography and, because they are often census records, give the same info every 10 years. I am not saying the data is not important, it is important to see children added and later disappear; it is important to watch the ages change, etc.
Lucyʻs suggestion of a Census Records section is easy and sensible.
