The fact is that we have a short window. Usually we know it has to take place within a period of, say, a week and a half—all three debates. It's a matter of negotiating with the parties. If one party is having its major and final mass gathering, we know it's not going to be that night. Similarly for the other party. We generally try to include a weekend, usually a Saturday, for the final debate, or a Friday. These are all high viewership nights, and we also try to slot the other two in the week before. That has worked out with the parties. The agreement is that both are going to claim they are suffering because of particular issues, but since both are suffering, they're willing to live with it.
