Estimated difference -0.40% on “revenue per visitor”, likely between -3.99% and +3.33% (95% range). Inconclusive: the range goes from -4.0% to +3.3%. It contains 0 but goes beyond the ±1.0% margin.
Planned sample size reached: the final range is the one that counts.
If the difference stayed at -0.4%, settling it would take a range of ±0.6% (it would fit within the ±1% margin of a negligible effect): 773 days in total, or 752 more, at the same traffic.
