 Trend Presentation
-------------------
-
-Performance Dashboard
-`````````````````````
-
-Dashboard tables list a summary of per test-case VPP MRR performance
-trend and trend compliance metrics and detected number of anomalies.
-
-Separate tables are generated for each testbed and each tested number of
-physical cores for VPP workers (1c, 2c, 4c). Test case names are linked to
-respective trending graphs for ease of navigation through the test data.
+^^^^^^^^^^^^^^^^^^
 
 Failed tests
-````````````
+~~~~~~~~~~~~

+The Failed tests tables list the tests which failed during the last test run.
+Separate tables are generated for each testbed.
 
-The Failed tests tables list the tests which failed over the specified seven-
-day period together with the number of fails over the period and last failure
-details - Time, VPP-Build-Id and CSIT-Job-Build-Id.
+Regressions and progressions
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-Separate tables are generated for each testbed. Test case names are linked to
-respective trending graphs for ease of navigation through the test data.
+These tables list tests which encountered a regression or progression during the
+specified time period, which is currently set to the last 21 days.
 
 Trendline Graphs
-````````````````
+~~~~~~~~~~~~~~~~
 
-Trendline graphs show measured per run averages of MRR values,
-group average values, and detected anomalies.
+Trendline graphs show measured per run averages of MRR values, NDR or PDR
+values, group average values, and detected anomalies.
 The graphs are constructed as follows:
 
 - X-axis represents the date in the format MMDD.
-- Y-axis represents run-average MRR value in Mpps.
+- Y-axis represents run-average MRR value, NDR or PDR values in Mpps. For PDR
+  tests also a graph with average latency at 50% PDR [us] is generated.
 - Markers to indicate anomaly classification:
 
   - Regression - red circle.
