I think it was done "right". The longer ago you go the less robust our documentation of it so compressing sparse records to make it more navigable is way more usable than vast swaths of empty pages of scrolling.
I also appreciate how they aren't really connected to each other to suggest a linear timeline of events. Nobody had infinite comprehension of all historical knowledge and simply hoisted themselves upon the shoulders of everything that came before.
Reality is super messy. Almost as messy as a jumble of people on a screen
The width of 100 years looks like it might be different each century.
