An example with real numbers

|---|---|---|
| Baseline | Logged where Start-to-Start (SS) stood before the test. | Something concrete to compare to. |
| Define | Fixed one meaning of Start-to-Start (SS) for the test. | Two people, one meaning. |
| Act | A streak-driven retention loop — one variable. | Only one thing moved. |
