Has anyone seen a reduction in motion detection?

Since I've rediscovered the forums as a great place to see if others are experiencing what I am I have one more question to ask. Has anyone else deen a reduction in the camera's ability to detect motion? I understand all about the angle of the camera etc. However, lately no matter the setting, the camera misses some fairly significnt motion. Anyone else?

Have you adjusted the sensitivity in your modes and rules? Have you used the motion detection test to determine how the camera is detecting and then trnasferred the setting to your  rules?
