I’m not going to expect a 16ms response or anything for every animation but much slower & you see jank.
For page interactivity though? 0.2s is pretty damn fast. Human response time is 0.15-0.25s
So it’s pretty reasonable

- photonerd 3y agoI’m not saying it’s fast. I’m saying that based on the goal of what it is measuring (user input responsiveness) it’s fast enough. For the purposes of the metric anyhow. Plus, speaking from far too long of a career dealing with user testing, respond too fast and users thing you didn’t actually do anything. So you’re kind of boned either way. This is just measuring programmatic delay.
