> It also seems to be a metric that is very easily gamed. Fun fact: the current JS-specific metric (which is being fazed out) is First Input Delay, and it was explicitly designed to avoid this gaming: > FID only measures the "delay" in event processing. It does not measure the event processing time itself nor the time it takes the browser to update the UI after running event handlers. While this time does affect the user experience, including it as part of FID would incentivize developers to respond to events asynchronously—which would improve the metric but likely make the experience worse.
