Name the task before departure
Before the first repetition, check who starts, with what action and to which zone. Clarify what the other person should do and when the roles reverse. An instruction that each partner reformulates differently is not yet shared. Errors do not always come from a lack of technique: they can come from a different understanding of the scenario.
Regulate honest cooperation
A partner can help understand a trajectory by maintaining a regular start. This does not mean that it should make all answers artificially successful. Conversely, secretly changing speed or technique is not a good test. The difficulty changes by mutual agreement with the teacher. Useful cooperation provides identifiable information, instead of manufacturing a victory or failure.
A stop must be immediately understood
The stop signal belongs to the framework of the exercise. Check that it is known and that everyone can use it. Discomfort, an incorrect distance or a forgotten instruction are enough to ask for a break. The partner should not have to justify himself at length during the action. After stopping, resume roles and distance before starting again; the movement does not start again by surprise.
Make precise and limited feedback
Describe an observation: “we were closer at the second start” or “you finished before my step arrived”. Avoid accumulating unrequested corrections. A single piece of information chosen by the teacher makes the next test easier. The partner is an interlocutor in the study; he is neither a mute target nor an improvised examiner.
Check understanding
Is secretly changing the exercise a good way to test the partner?

No. A variation becomes useful when it is part of a known and adapted framework.
