Have you noticed a change in the behavior of google pagerank?

I have noticed a change in Google Pagerank behavior and I wanted to know if it was the only one.
Before it was possible to point out all the links generated by GSA SER to the home page and the google juice was extended by the website. Now, I have the feeling that it is more efficient to point to each URL.
For example, it has a homepage about tire types and a subpage about how to change a tire. If you aim directly at changing the tire, you will get more traffic than if you sent the generated links to the home page.

I also noticed that it was now useless to create many backlinks to a page with thin content (few sentences, only one image, category page).

What you think? Did you notice something like that?
