How to use this result
Changing five things at once makes the next morning impossible to interpret. This experiment creates a seven-night sequence where one main bedroom cue changes while the rest of the routine stays boring and repeatable.
It is useful after a single calculator result because it turns the advice into a small test. Night one is the baseline, nights two to four repeat the change, and nights five to seven check whether the pattern is stable or just random.
Keep notes simple: light level, phone boundary, room feel, window moisture and wake quality.
Best use
Run the tool, choose one change, repeat it for two or three nights, then compare the room notes. A repeated pattern is more useful than one perfect-looking number.
