I would agree with this, but unfortunately that would be skewed by the fact that the continents that did not have special rules to them that would possibly affect the results. Beluaterra is an immigration only continent. You have to move a character from somewhere else to there. The other continent that wasn't affected, the Colonies, has only one turn per day, so the activity would significantly be affected by that.
Noble count and density are the only metrics I'd really like measured in this regard.
"Did reducing the size of some of the continents allow them to retain greater density than the continents that were not reduced" is the hypothesis to test. It doesn't matter if it's apples and oranges between the continents, what's important is not the raw value, but that variation ratio.
