Remarks :
- We see that the grades are squeezed together for the opponent.
- They follow a pretty nice gaussian law for the reporter, with a small rebound at 9/10. This can be easily explained by the fact that judges indeed hesitate to put the best grade, because they know that it is the last one they have.
What should we do ?
- For now, the differences between teams only happen on the quality of the presentation, the role of the opponent having only a very small impact. To render both roles useful, we should want to add something in order to make the opponent's role stand out.
- In order not to penalize the best reports, we should also want to remind the jury that the median grade is 5, and that they should not hesitate if they believe the presentation was very good (give them a star card for amazing presentations ?)
