Silent Round Analysis
Watch a full recorded round, flow all of it, then write the ballot: who won, on which argument, and a paragraph defending the decision the way a judge would.
Choose a recorded round; elimination rounds from major tournaments are ideal. Flow the whole debate without pausing, the way a judge would hear it.
Before you hear any real decision, write your ballot in the language a judge would use: who won, which argument was the voting issue, and why. Note where each team lost you, whether it was a dropped argument, an extension with no explanation, or weighing that never happened.
If the round has a published decision, compare. Where you and the judge disagree is where your model of judging needs updating. Debaters who think like judges make strategic choices, like what to collapse to and which weighing to prioritize, that other debaters miss.
