How it works
Set sample, pass rate and duration
Fix the participant count, minimum success rate and timeframe before launch, so the decision rule can't move after results arrive.
Get a calculated threshold and pace
Sample times pass rate gives the minimum successful observations; sample divided by duration gives the daily recruitment target.

Frequently asked questions
Is this a statistical power calculator?
No. It creates a practical early MVP decision rule; small effects or high-stakes tests need formal analysis.
What counts as success?
Use observable behaviour such as paying, booking or completing a task, not general enthusiasm.
Can interviews use a threshold?
Yes, when success is a repeated behavioural pattern defined before interviews begin.
What if the test misses?
Record the result and revise, retest or stop without moving the original threshold.
