Need help regarding finding sensor offset using a TLE5012b quadrature encoder sensor.

I have referred to the quadrature encoder calibration method that uses a LUT to find the sensor angle. But I'm following a different method to find the offset. First rotate the motor clockwise twice with a fake angle and measure the error with the measured electrical angle and store the error over time and average out. Do the same for anti-clockwise and store the error and average out.

This method gives me inconsistent offset angle.

Do I need to align to a particular electrical angle in the initial stage?
