I would rather see a scale of 1 hex to 5 miles at the kingdom level. That allows one village to each hex for an area that's densely populated (by medieval standards), and will make it obvious where areas are less heavily populated. It's not a bad size for geographic features too. And while it'll mean large kingdoms take up more than one sheet, that's also true at the 1h:10m scale too.
There should probably also be mention of "World" scale mapping. I like to play around with continent locations on a world map, so that I'll have an idea of the latitude something is at and some idea of wind patterns, ocean currents, and mountainous regions. That way I can judge the type of environment an area is likely to have, instead of placing things as randomly as some map-makers/world-builders seem to.
