Event markers are detected with relative degrees of confidence (between 1% and 100%). You can filter out extraneous Event markers by adjusting the Event Sensitivity setting in the Elastic Properties window; event markers with the least confidence are filtered out first. However, some significant events may not be recognized with a high degree of confidence. In this case, you may want to promote the Event marker to ensure that it is not filtered out when reducing the Event Sensitivity setting. Promoted Event markers, like manually created or moved Event markers, have 100% confidence.
