When a fourteen-day extension may help
A longer confirmation round may be useful when daily ratings vary widely or the activity is hard to practise regularly.
Commit to the same small action for fourteen additional days only if it remains manageable.
Open my labWhat to notice
Look for repeated direction and practicality, not merely a better final day.
Record a 1–10 daily rating and whether you tried the activity. A missed day is useful context; it does not erase the rest of your week. At the first checkpoint, you can continue for seven or fourteen days, or choose something else.
How to interpret your result
Longer tracking can become burdensome. You can stop or change experiments whenever needed.
Keep your original prediction separate from the daily ratings. Your starting rating, number of observations and changing circumstances all matter. A personal week can reveal a pattern worth exploring, but it cannot establish cause or statistical significance.
