art........ every one has their opinion
It is important that you have a reason why you do what you do.
Old papers on PCB layout are OK, funny old man on the internet are probably OK.....You have to use your head and make choices.
At first you only have what you read to guide you but soon you will be making choices based on what you think.
all wise do it this way.............
NO...do it smart. Only you understand you design.
You will make mistakes. Other people will disagree with you. There are many ways that work. (
not just one)

Years ago we made a board that needed to be very quite. There was a big fight as to where to connect the PCB to chassis ground. There are a number of bolts that held up the board. I conducted a survey with all the engineers. I wanted to know which ground point was best, and which was worst and why. Then for a week I conducted tests. I tried one point grounding at each standoff (bolt) then I tried two point, three point.....I tried all point grounding.
The results was that every "good point" was good. Each "bad point" was bad. So the thinking of each engineer was right. (different but right)
The real surprise was that all points grounded worked very well. (I was not surprised) With all points connected to the aluminum it forced the aluminum to look like another ground layer.
Results; the grounds should either be smart or strong.
