That's all. That was context.

Definitely.

ok here why I gave context.
Some of these sites (example CNet) have a tendency to send very different 
content based on UA sniffing, JS script path, etc. etc.  So when testing in 
Gecko devtools, the results might differ for some of the findings because 
anyway Gecko does not receive the same thing. :/

Also devtools are sometimes not neutral themselves with regard to the analysis. 
Another layer of variability. 

But yes 10000+ very interesting study. 
To reinforce the point that rob made: Slow Web == Ads Quantified Web. Things 
like µblock helps to understand how fast the Web can be ;)
