In LD I am a tabula rossa traditional judge that decides on values, criterion, solid contentions, and warranting. Spreading and aggressiveness will lose speaker points.
In WSD, I am a tabula rossa judge in terms of reasoning. Spreading and aggressiveness will lose style points. RFDs are based on principle and practical substantives, reasoning, examples, evidence (where appropriate), models (where appropriate), burdens, weighing and clash.
In PF, I am a tabula rossa judge that decides on contentions that are brought through the round and contentions that are dropped (You have to argue whether they are critical or not). Rounds are based on reasoning and relevance of the evidence presented.
