Your three-week timing experimentSix comparable posts, two windows, one metric, one honest decision.
Experiment · X · three weeks · audience local time
Window A · Tuesday, 09:00
Window B · Thursday, 18:00
Schedule · Week 1: A then B · Week 2: B then A · Week 3: A then B.
Control · Keep topic, format, quality, and call to action comparable. Record every result after exactly 24 hours.
Decision rule · Compare median meaningful engagement rate. A difference below 20% means there is no clear winner yet.
How this works
The planner creates two audience-reasonable windows and alternates them across six comparable posts. It never claims to know your audience activity without connected account history.
Assumptions
- All times are interpreted in the audience’s local time.
- The six posts use a comparable topic, format, and quality level.
- Each result is recorded after the same 24-hour observation window.
Limitations
- This is an experiment plan, not a personalized prediction.
- Small samples can produce no clear winner.
- Platform distribution and audience behavior can change.
