C.39:4.1 - State the local result and try the cheap exit
Say what should change or become available, for whom or for which use, and which observation would distinguish an adequate result. Include a constraint when violating it would defeat that use. “Improve the recording” is too broad if the live question is whether movement and sound remain within a stated timing tolerance.
Look first for an applicable Method or an already available result that answers this question. Inspect the operation and its qualifications, not just its title. Use that answer when it is sufficient; there is no requirement to invent a second way, perform an experiment or produce another account.
An available partial result may also let the work stop. If only the next inquiry must be chosen, do not demand the explanation needed for full deployment.
