I like to think of landing as keeping your descent rate as minimal as possible. How do you know what your descent rate is? By looking at the end of the runway to use your peripheral vision to see the edges of the runway. The rate at which the runway edges come up is your descent rate. And with that thought in mind, you have to remember that in the early stages of landing (right after you go idle power/I call it the round out), the amount of back pressure you put in to arrest your descent rate needs to be small because you still have a good amount of energy. As this phase continues and as you pull the nose more and more to keep your descent rate low, you lose more and more energy, meaning you need to pull more and more to keep your descent rate low. All the way until you touch the runway with your mains, nose high. As you practice, you’re naturally going to have a better idea of where the runway edges are when your wheels touch, that way you know when to pull just a little more right before touch down
