 ## Configure timing and trace profiling runs
 
 For complete analysis you must run two experiment types:
-  * Timing-only runs — no kernel trace logging; use these for accurate latency comparisons (SME2 on vs SME2 off).
-  * Trace-enabled runs — enable XNNPACK kernel trace logging; use these to collect kernel-selection evidence and traces for kernel-level analysis. Trace logging affects timing and should never be used to compare end-to-end latency.

 Run timing-only for latency measurement, and run trace-enabled only when you need kernel-level details.
