 _**Important:** CLS should be continually monitored for changes throughout the entire lifespan of a page—including if the user returns to the page after it's been hidden/backgrounded. However, since browsers often [will not fire additional callbacks once the user has backgrounded a page](https://developer.chrome.com/blog/page-lifecycle-api/#advice-hidden), `callback` is always called when the page's visibility state changes to hidden. As a result, the `callback` function might be called multiple times during the same page load (see [Reporting only the delta of changes](#report-only-the-delta-of-changes) for how to manage this)._

 A custom `durationThreshold` [configuration option](#reportopts) can optionally be passed to control what `event-timing` entries are considered for INP reporting. The default threshold is `40`, which means INP scores of less than 40 are reported as 0. Note that this will not affect your 75th percentile INP value unless that value is also less than 40 (well below the recommended [good](https://web.dev/articles/inp#what_is_a_good_inp_score) threshold).
