You cannot tell whether a waitlist is working from the feeling at the front desk. This log records every spot that opened in a full class: when the cancellation landed, how many people were waiting, how the spot was offered, how long it took to fill, and what happened on the day. Keep it for a few weeks before any change to build a baseline, then keep going after launch and compare the two periods by class format and time slot. The pattern usually shows that a few classes and a few times of day account for most of the empty spots, which is what lets you fix the policy narrowly.

The example rows show how to fill it in and are only illustrations, not benchmarks; replace them with your own entries. Weekly totals for cancellations per class and the share you managed to refill can go straight into the Late Cancellation Revenue Leak Calculator (/tools/late-cancel-revenue-leak/). The waitlist depth column feeds the Class Waitlist Depth Planner (/tools/waitlist-depth-planner/), and once you have a month of entries under automation the Waitlist Refill ROI Calculator (/tools/waitlist-refill-roi/) will show whether the numbers hold up. The guide (/guide/) explains how to read the results.
