Was this even an issue, or could it be easily resolved if it does present a problem?

Since you only have 2 transitions, it would be better to space the disc off the actual distance so the image is not focused. When the encoder dist was spaced correctly, it was picking up an extra tick from a scratch on the aluminum. We put the disc closer to the sensor to make it blurry so it does not pick up small scratches.
