Touchweight, speed of depressing piano and dynamics

Do you find that some pianos seem easier to play and use less force to depress the keys? I find a article discuss about this phenomenon. The writer says it is all about touchweight and piano action.   He gives a very detailed explanation about this topic. Please have a look:

And this is further study of touchweight. We usually have the myth that we use different degree of force on pressing the piano keys to give dynamic change. However, from Thomas Mak’s Alexander Technique book What Every Pianist Needs to Know About the Body, he says  “The very important thing that the pianist needs to know is that it is not the pressure applied to the keys that determines the volume of the sound, but the speed with which they are depressed. This may be surprising to some pianists, but it is the truth.”

This idea is odd and abstract. So at first I would ask my students just use their hands knocking  at the piano cover or any wooden surface. Knock slowly and accelerate the speed gradually. Let them listen to the change of volume of knocking sound with the change of knocking speed. Only after they can manage it we move to piano playing. This time we play only on one piano key, also starting from very slow finger action and accelerate.
