REPLAY / ex-001
Two-column signup form
Reviewed as if it had not run yet. The coach sees only experiments that read out before 2024-01-29.
01 THE EXPERIMENT, OUTCOME HIDDEN
HYPOTHESIS
If we split signup across two columns instead of one long scroll, more people finish it, because the form stops looking long.

The coach will see only what this team knew before 2024-01-29. You answer, then the real outcome is revealed and the call is scored.
