there's a lot more than just throttle position that goes into calculating target throttle plate angle in any given situation. a simplification is to say that requested torque is resolved from a 3-dimensional map of accelerator pedal angle and rpm, which is then used in another map to look up a target throttle plate angle. in reality it's more complex than this, with other maps involved that i don't understand. point being you can't expect a steady input to result in a steady output.
