After 200 jumps in this sport, I have finally found out how to sink my canopy in using my brakes, just like what was explained. I had a horrible time with accuracy (I always made it back to the DZ but landed in an area further out to avoid all the people) and now by using those techniques I can land safely in the area that I want to.
Don't forget to practice up high! I've never collapsed my canopy by sinking it in but I am fully aware of what could happen and constantly re-evaluate what's happening during my approach.
