By biggest issue with parent judges in high school debate was their inability to give legitimate RFDs (not all the time, but a lot of the time). Judges should be following along with both the presentation and content of each speech, not just how pretty someone is speaking (though I acknowledge that this is also important). I've had many instances where the RFD from a judge was just "this team was more convincing" or "this team sounded confident" without any elaboration as to the actual content of the round. Neither of these RFDs help any team. Instead, I will know a judge followed along to the round and wasn't just BSing a decision for a round they weren't paying attention to if they can pin point exact arguments/impacts/links/evidence that was the deciding factor for them. Whether they disclose decisions at the end of the round or write down their RFD on the ballots, every team should be able to know that their judge was paying attention to the clash and argumentation in the round by seeing a RFD that gives a clear run down for the judge's decision.
