I sleep 6 hours but analyze: should I try sleeping more? Map the current state: performance, mood, health on 6 hours. Calculate: if I extended to 7 or 8 hours, would function improve? Show me the extension trial: add 30 minutes for 2 weeks, assess changes. Give me the testing protocol: systematic extension and measurement. Include: whether I'm sleep deprived or efficient sleeper, how to test need, and if more sleep would help.
