Another thing Pat re: the JS/CSS combine.
If the browser is using the 6 connections to fetch CSS and JS files, it cannot fetch other assets. That is another reason to do combining.
- 1x JS
- 1x CSS
those start loading while HTML is coming in
Browsers have 3 connections left for fetching other assets, probably images.
Once HTML is in - and JS and CSS stil loading - another connection is available for fetching a resource.

But .... you may not always want to combine all CSS and all JS into one file, *especially* if you are putting that big JS file in the HEAD.

Re: the JS files at top of BODY ... I've seen the grade not being F often, so probably those JS files were high up in the BODY but bot blocking rendering entirely. From what I remember, nothing really was rendered, so the UX was bad, but yeah ... WPT can't know that.

Now how to create a good rule for this?
BTW, I totally agree on this:

"The grades have always been the "these ALWAYS apply and fix these before you even consider looking at anything else" issues and I think the JS/CSS combining is losing some of that certainty."
