That was my first impression too but then I thought about what it’s actually measuring: page responsiveness, not animation jank.

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

.2s is slow for a redraw. Just because it might take you 200ms to click after something happens doesn't mean you can't see/notice when things take that long.

I’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.
