Final Approach
I know it's your poll, but I think I am not alone in my category of doing primarily business flying but not in a company plane, where all business flying is covered by the business. I don't see how any of your categories is not in direct (and important) conflict with this.
Sure, the wording is not perfect. But if you fly in the course of earning an income and take some or all of the flying expenses as a tax deduction as a business expense then, for the purposes of my poll, it is the same as if you flew for another firm or business either frequently or occasionally so categories 3 or 4, respectively. That's the best I can do at this point because I can't change the poll once it's created.
