If a user watches a video with event tracking three times in a single session, how many Unique Events will be counted?

When utilizing event tracking in Google Analytics, a Unique Event is counted when a specific event occurs for the first time within a session, regardless of how many times that event occurs afterward in the same session. In this scenario, when a user watches a video with event tracking three times, only the first occurrence counts as a Unique Event for that session. Thus, the total count of Unique Events would be one, reflecting that this specific event was triggered only once during the session. This counting method helps in understanding user interactions without inflating metrics based on repeated actions within the same session.
