Confidence is against the current version. The upright mark is the 95% a version needs at the planned end to be called the winner; before then it is a reading.

How experiments are judged
  • The current version always runs alongside the challengers, so results are compared fairly.
  • A test is called once, at its planned end: a version wins only at 95% confidence or more, with at least 20 conversions in every version.
  • Before the planned end, a lead can still reverse, however strong it looks, so the test isn't called early.
  • If nothing clears the bar at the planned end, the current version stays.
