Why is the "Strengthen skills" useless for visual advancement

Using the "Strengthen skills" button just gives me various different sentences that duolingo says I'm "struggling" with. However, no matter how perfect I do it gives me the same exact things over and over again and doesn't strengthen my total spanish skills.
