 Description
 -----------
 
-Dashboard tables list a summary of per test-case VPP MRR performance trend
-values and detected anomalies (Maximum Receive Rate - received packet rate
-under line rate load). Data comes from trending MRR jobs executed every 12 hrs
-(2:00, 14:00 UTC). Trend and anomaly calculations are done over a rolling
-window of <N> samples, currently with N=14 covering last 7 days. Separate
-tables are generated for tested VPP worker-thread-core combinations (1t1c,
-2t2c, 4t4c).

-      iii) highest progression if progressions detected, iv) nil if normal i.e.
-      within trend.
-    - "Anomaly vs. Trend [%]": anomaly value vs. trend value.
-    - "Classification": outlier, regression, progression, normal - observed
-      over a rolling window.
-    - "# Outliers": number of outliers detected.

+    - "Trend Compliance": calculated based on detected anomalies, listed in
