Exactly how often micropauses occur will obviously depend on your WorkPace settings. However, even with the same settings there can be a tremendous variation and how often micropauses are prompted. Many people will only see a few micropauses an hour at most. This is because WorkPace detects natural pauses in your and resets the micropause timer. However, in times when you are working very intensively, perhaps towards a deadline, you may be taking less natural breaks, meaning that you will be interrupted more often by WorkPace.
