Hey Brian - can you post a link the wpt result that is showing a bad score? And which score specifically?
Keep in mind google’s page speed insights scores don’t always mirror a better user experience (although I’m sure your server push is a step in the right direction)

Using lighthouse as testing we get really good scores so I just dunno what to think.
Which test is the best ??
Lighthouse? WBT? Google pagespeed insights?
Smoke signals?
That’s actually pretty typical. Page performance can vary widely from day to day on some servers. And depending on what public test agent you get sometimes they’re less powerful than they should be.
Ways around this are to have it run multiple tests and use the median result, set up a private instance and ensure you’re using beefy agents (c4.large or better if you’re on EC2), or use a 3rd party service to monitor regularly.
