Changing numbers of render-blocking JavaScript and CSS I have a drupal 7 site.
I use the Advanced CSS/JS Aggregation module

In the past I asked this question, and tried to improve performance and "Eliminate render-blocking JavaScript and CSS in above-the-fold content" as Google Page speed test suggested.

After I got answers to the question I changed the module configuration, and set the Target Number Of CSS &amp; JS Bundles Per Page to be 4.

For some reason, now, when I am running speedtest, I see that I have "9 blocking script resources and 5 blocking CSS resources" instead of 4 clocking for CSS and 4 blocking for script.

Why is that happening?
How can I fix it, and make the advagg configuration work?
The bundler works per region, so set it to 2 for JS as you have footer JS and header JS; 2 header + 2 footer + 2 external scripts will give you 6 for desktop and 3 for mobile, as Page Speed Insights seems to only count header JS for mobile. Moving all the JS to the footer might help eliminate all render blocking JS with mobile according to Page Speed Insights Mobile; it will also give you a better score for the Page Speed Insights desktop as more JavaScript files can be combined.

You can disable the bundler as that will give you a better score, but you will have to download a new full sized CSS/JS aggregate if any of the CSS/JS changes per page on your site; so you won't be able to fully take advantage of the browser cache and real world performance will not be as optimal as it could be if you do disable the bundler. It's about tradeoffs.
