Cool to hear from someone who worked at Yottaa! We have seen that solution before, but it seemed like it's mostly timing your third-parties to be loaded with some delay? So more like optimizing when to load a script, but still loading the same script. The website is a little vague. Our analyzer shows that third-parties are slowing their website by 61%, which is way more than the average, so I get the feeling that this doesn't work too well. But yes, you're very right - we're super focused on Core Web Vitals.

I could elaborate more if you’d want to chat. You are correct for the most part, at a high level. They focus on the browser load event.

Would be happy to - I'm reachable at yoav at zaraz dot com. Thank you!
