Evidence, in policy debate

That's a misleading statement because you don't mean policy debate but the format of US high school policy debate. British Parliamentary Debate (BPS) the format in which the World Debating Championships are held should be considered as being a "policy debate".

In BPS you don't have to address inconsequential points but you focus on the most significant points the other party makes.

This feel a bit like an American complaining about how difficult it is to calculate with imperiral units while being oblivious to the fact that the rest of the world uses better standards.
