I think the other thing is I find it hard to remember what the core web vitals mean, and to relate them to what's going on.

When we used to measure TTFB, DomContentLoaded and page fully loaded, I understood what those meant and could relate them to what's going on on-screen.

The core web vitals are a bit abstract to reason about - and how they're linked. FCP vs LCP, how they interplay...

I'd like a video where a page loads and PING! a vital happens, the page pauses and someone talks about that vital, what's led up to it, what's affected it and what would change it. Then the page unpauses until the next vital is reached. Something to make it relatable.
