+  The current overload compensation algorithms works on fix steps which leads to the fact that in the high velocity

 - [ ] **Improve rim shot detection**
 
   Especially for pads like the PDA-120L where the piezos are located near the edge, the rim shot detection does perform poorly.
-  The rim shot detection for non-rim-switch pads is highly influenced on the overload of the ADC. This has to be investigated
-  (i.e., that loud strikes on the middle of the mesh head triggers a rim shot because the clipped head signal is lower than
-  the true peak and therefore we could get over the rim shot threshold since the rim trigger is not overloaded).
+
+  It seems that the previous assumption about overloaded signals influence the rim shot detection performance is not true.
+  Setting max_num_overloads=0 does still give false rim shot detections on the PD-80R in case of loud strikes in the middle
+  of the pad (I assume that hitting the piezo cone directly causes the problem).
+
+  A quick test showed that rim_use_low_freq_bp=true works better on the PD-80R and also if I do not disable rim shots
+  if is_overloaded_state than this does not change the rim shot detection behavior on, at least, the PD-80R.
