This was a fundamental challenge for us in designing this system, because the self-employed do not have an objective record of the hours they work, which regular employees do. Regular employees contribute based on the hours they have worked, the hours for which they are paid, as you're aware, which are verified by their employer. Whether it's a work week of thirty-seven and a half hours or they get paid on an hourly basis, all of those hours are recorded.
The self-employed don't have records like that, not that we can objectively verify. So what we would try to do is say, okay, what's the closet approximation so that we're not excluding people? We've said that since 600 hours can't be used, which is the standard we've used for regular employees, how do we approximate that? We wanted to make sure that we didn't set the standard too high or too low--
