Is the turnover rate required for Unity PRO to come explicitly from game sales?

As a private person with an unrelated day-job I plan to sell an App or two. Of course, I do not expect to hit the current $100000 limit from the App sales. But the question is if the revenue in question is connected to the business you are directly using Unity for making money. I would assume this, but if these earnings take into account the entity as a private person in total, and other (unrelated earnings), this could be an issue.

Set up a small company to sell the game, and use this company to purchase the Pro license when your game/company makes $100k turnover.
