Six straight points below the frozen median
Illustrative weeks for a fictional four-provider primary care practice, Wrenfield Family Health, testing a two-touch reminder workflow against its weekly no-show rate.
| Week | No-Shows / 240 | Rate | vs. Frozen Median (13.75%) | Run |
|---|---|---|---|---|
| 16 | 27 | 11.25% | Below | 1 |
| 17 | 25 | 10.42% | Below | 2 |
| 18 | 24 | 10.00% | Below | 3 |
| 19 | 22 | 9.17% | Below | 4 |
| 20 | 23 | 9.58% | Below | 5 |
| 21 | 21 | 8.75% | Below | 6 (shift confirmed) |
Six consecutive weeks below a median a 12-week baseline froze before this reminder workflow started is a shift, per the run chart's own rule. Weeks 13 through 15 do not appear here: the second of those three came back above the median, so cycle one alone had not yet cleared the threshold.
