I would limit it, more like this
1. Was the official on time? Did his appearance meet your expectations?
2. Does the official communicate well with the participants?
3. Does the official communicate well with the table crew? With you and other game supervisors?
4. Did the official keep control of the games?
5. Do the official's calls match the game?
6. Does the official help you keep things running on time?
7. Other comments?
