Output from Ideal rotational motion sensor

I have designed a BLDC motor with 6-step control algorithm. Inorder measure the angular velocity from the physical system I have used Ideal rotational motion sensor , I'm trying to understand whether the ouptut from the port A - angular acceleration port will be high precision value or low precision value.

The Ideal Rotational Motion Sensor block represents an ideal mechanical rotational motion sensor, that is, a device that converts an across variable measured between two mechanical rotational nodes into a control signal proportional to acceleration, angular velocity, or position (angle). The output is as precise as could be and there is no dynamic or delay that would normally be observed in a real-world sensor.
