Why does Animator.targetRotation change every frame?

Unity Engine
1

Here is my test code:

Animator animator;

void Start()
{
    animator = GetComponent<Animator>();
    animator.SetTarget(AvatarTarget.Root, 1);
}

void Update()
{
    Debug.Log(animator.targetRotation.ToString("F4"));
}

I have this attached to a human character that just walks in a straight line (actually he turns back and forth while walking, but is facing the same direction at start and end of each loop). I thought animator.targetRotation would continue to return the same value as long as SetTarget didn’t change.

I’m trying to figure out “at the end of the current animation state/loop, what position will my character be facing”. Is this not the correct method, and if not, is there another way or does this info just not exist?

Upon further inspection the values are only changing by a small amount. I’m not familiar with quaternion values since I hardly ever use them or see them. Once I changed my debug to log eulerAngle instead, it became obvious that the values were only changing slightly, like 179.9 to 180.1. Acceptable for what I need.
