Judge the sequence, not the scramble
Most arguments happen because players focus on the scramble instead of the order of events. The speed of the point is not the important part.
If you check the serve itself first and then ask whether the ball took a second floor bounce before a legal return, most disputes become much simpler.
- Confirm the serve itself was legal.
- Confirm the first bounce landed in the correct service box.
- Confirm whether the receiver had a legal play before the second bounce.
- Award the point once the second bounce ends the return opportunity.
