PPT presentation experience

A few days ago, I presented a presentation with my colleagues at the client. I mainly used ppt files to record some of my experiences:
1. Who will demonstrate who will make a PPT
2. Show employees rather than the boss.
3. necessary disciplinary constraints should be imposed on the presentation venue
4. constantly adjust the content of the PPT according to your understanding.
5. Record the outline of the PPT on a piece of paper to control the overall progress.
6. Any PPT should echo each other and be overly soft.
7. Avoid any predicate explanation
8. During the explanation process, the voice should be loud, the attention should be concentrated, and the speed of speech should be effectively controlled.
9. Do not wear casual clothes for the demonstration staff
10. Adjust the speed based on the customer's situation. Try not to make it too fast.
