please tell me why there is such a big difference between the included "Total Blocking Time" on the site https://developers.google.com/ and the local litehouse for a mobile device?
I am not able to give you the address and show you the site, there is just a text and a picture. The site is made on nuxt js and assembled completely statically.
My computer - mackbook air m1, google uses less powerful emulation and results in fewer parrots?
This official page explains it well: https://web.dev/performance-scoring/
Otherwise, this one is another answer: https://www.debugbear.com/blog/why-is-my-lighthouse-score-different-from-pagespeed-insights
Google PageSpeed uses a “combo” of lab and real-world data[historical data of your website], whereas Lighthouse uses lab data only[locally tested on your machine] to build its report.
Note: You should trust PSI metrics over just lab data.
