At Yamaha they have an aftertouch of 0,4 mm. Press lightly on the key so that you barely see the white under your nail. The hammer should move upwards just a tiny bit (0,4 mm) That is an average. You can opt for a "hard landing" with hardly any aftertouch, or a "soft landing" with more than 0,4 mm. MOre than a full mm results in a waste of movement, energy, and tone.
