-Dashboard tables list a summary of latest per test-case VPP Maximum
-Receive Rate (MRR) performance trend, trend compliance metrics and
-detected number of anomalies. Data samples come from the CSIT VPP
-performance trending jobs executed twice a day, every 12 hrs (02:00,
-14:00 UTC). All trend and anomaly evaluation is based on a rolling
-window of <N=14> data samples, covering last 7 days.

-Legend to table:
-
- - **Test Case** : name of CSIT test case, naming convention in
- `CSIT wiki <https://wiki.fd.io/view/CSIT/csit-test-naming>`_.
- - **Trend [Mpps]** : last value of trend.
- - **Short-Term Change [%]** : Relative change of last trend value
- vs. last week trend value.
- - **Long-Term Change [%]** : Relative change of last trend value vs.
- maximum of trend values over the last quarter except last week.
- - **Regressions [#]** : Number of regressions detected.
- - **Progressions [#]** : Number of progressions detected.
- - **Outliers [#]** : Number of outliers detected.
+Performance dashboard tables provide the latest VPP throughput trend,
+trend compliance and detected anomalies, all on a per VPP test case
+basis. Linked trendline graphs enable further drill-down into the
+trendline compliance, sequence and nature of anomalies, as well as
+pointers to performance test builds/logs and VPP (or DPDK) builds.
+Performance trending is currently based on the Maximum Receive Rate (MRR) tests.
+MRR tests measure the packet forwarding rate under the maximum load offered
+by traffic generator over a set trial duration, regardless of packet
+loss. See :ref:`trending_methodology` section for more detail including
+trend and anomaly calculations.
+
+Data samples are generated by the CSIT VPP (and DPDK) performance trending jobs
+executed twice a day (target start: every 12 hrs, 02:00, 14:00 UTC). All
+trend and anomaly evaluation is based on an algorithm which divides test runs
+into groups according to minimum description length principle.
+The trend value is the population average of the results within a group.
