 Throughput Trending
 -------------------
 
-In addition to reporting throughput comparison between TRex releases,
 CSIT provides continuous performance trending for master branch:
 
 #. `TRex Trending Graphs <https://s3-docs.fd.io/csit/master/trending/ndrpdr_trending/trex.html>`_:
    per TRex test case throughput trend, trend compliance and summary of
-   detected anomalies.
+   detected anomalies. We expect TRex to hit the curently used bps or pps limit,
+   so no anomalies here (unless we change those limits in CSIT).
 
 #. `TRex Latency Graphs <https://s3-docs.fd.io/csit/master/trending/ndrpdr_latency_trending/trex.html>`_:
    per TRex build NDRPDR latency measurements against the trendline.
+   We have seen in past that the latency numbers can depend on TRex version,
+   NIC firmware, or driver used.
