 > !! if beetle runs in circle it is in "escape/panic mode" which doesn't represent "natural" behaviour (explore, forage, quick move from a to b)
 	-> think about different setup. Bigger Arena?
 --> ! beetle needs to be small enough to not be limited by constrained size of the arena
+
+> how much time for beetle to calm down / aclimatize? 10mins?
 > 10 minutes is enough to analyze movement
 > 8 fps could be enough to reduce mean error
