How is that data compiled? Just poking around, the worst site in the list (SFGate) seems to have gotten a "1" for performance every time it's been tested, but when I try checking the same link in lighthouse (mobile mode) it scores 55~60.

CWV metrics are gathered and aggregated from field data with the variety of devices and internet speeds you would expect in the wild.

  I was asking about the lighthouse results in the link in GP's post, is that what you're answering?

    Oh, my bad! Last time I checked, Lighthouse in Chromium used (by default) a Moto G4 on a mobile network simulation.

Uses Google Lighthouse. Takes average of last 3 days worth of tests. Each site usually tested 1-2 times per day. All the data is here: https://docs.google.com/spreadsheets/d/1sGKmbnW74u9r1GOzAQcIl3tAdLPLQ7ZkDMK2uR2HYfA/edit#gid=1647776330 https://docs.google.com/spreadsheets/d/1sGKmbnW74u9r1GOzAQcI...

  That's the data I asked about. That data shows SFGate repeatedly getting a 1, but when I try the same test it gets 55-60?

    There is no one lighthouse number. The site is likely using their own scores that are based on (but not direct averages of) lighthouse. Perhaps they give a score of 1 to the lowest site and scale up.

      We're talking about the numbers that show up in the results of a lighthouse "performance" test. The overall score, total blocking time, time to interactive, etc. The spreadsheet has columns for all those values, and it shows SFGate consistently getting a "1" as its overall score. (It's "0.01" in the sheet, as I guess it considers the scores percentages.)
