I bet each one believes there’s a special way to press that button. Such as:

Rhythm

Frequency

Amplitude

Maintained Pressure

Striking force

Finger curl degree

Number of fingers

Finger position on the buttons surface

Finger distribution over the button

Button tilt factor (starting point of actuation vs the point of departure)

Palm shape

Bent at the wrist or maintain a stiff rigid arm

Its either a fucking science… Or it could be a video game simulator.
