I want to make things clear here:
I am not saying that intensity-based methods don't work. They do. I recommend young, new lifters to follow some sort of linear periodization scheme and try out all different kinds of exercises.
I am saying that for many, especially older lifters, or athletes from other sports, or folks with a lot of mileage on them, letting the volume do the work using an approach like this allows them to progress while feeling less beat up from the work.
I was recently told that the Icelandic deadlifters train in a similar fashion, and sneer at pulling maximal weights outside of competitions and mock competitions. They do their work, they keep their bar speed high, and they deadlift on Mondays to when they are freshest (Dave Van S. had some stuff on this recently)
