The "lay" debate formats have the same technical rules as policy debate, theyre just shorter and dont lend themselves to spreading. Policy debaters clean up because theyre playing debate in hard mode, but the rules are still similar: present contentions, rebuttals, and anything that isn't addressed carries across the flow and is tallied up in the end as a mathematical formulation of who addressed which points when, and were those rebuttals convincing? Theres no room for the soft skills required to legitimately influence people in real life, the most important of which is listening.
