You are most right, we fell behind significantly for some reason since I last checked.
That reason is that "PSI estimates this page requires 4 additional round trips to load render blocking resources and 0.4 MB to fully render. The median page requires 4 round trips and 2.7 MB. Fewer round trips and bytes results in faster pages."
This is easy enough to fix, and I'm glad to know about it. Its on the top of my list, category: google related stuff.
