The operator inspected an illustrative fixed-horizon pack: 80,000 planned users, 31,200 observed at day 11, four unofficial looks, a 2.4-point day-11 delta, a 0.6-point day-28 delta, and unchanged refunds. Day-11 shipping and the final decision remained held as exploratory.

The [CSV](https://infinisynapse.com/blog-media/ab-test-sample-size/downloads/stopping-summary-ABSS-PEEK-20260823.csv) exposes six aggregates and two held decisions. The [verification script](https://infinisynapse.com/blog-media/ab-test-sample-size/downloads/verify-ABSS-PEEK-20260823.py) checks displayed output only.
