R1200GS Cruise Control testing. Pushing button forward or backwards fails to incrementally accelerate or decelerate as expected. Press and Hold works okay. Instructions from the manual are at the beginning of the video. Press Pause and read it if you are not already familiar with how it is supposed to work.

Final Analysis after much testing: I am pressing the button too long. You must tap the lever very quickly to bump the speed up / down! 1/2 second or more is too long.
