 * target SDK level 35
 
-* minimum amplitude for accelero
+* record the accelero and check why repeated fast beats result in occasional detection outages
+    - guess: the threshold gets pushed so high that the later beats are not detected properly
+    - maybe we need the `*0.6` factor after all (but verify this!)
+
+* minimum amplitude for accelero (avoid detecting e.g. when phone is lying flat and you hammer on the table)
 * filter away bad SQI areas of the signal (do not detect steps if we have bad SQI)
