Avatar Mask Improve performance?

Hello guys,

So I check the Unity Avatar Mask Document. It said it can tend to reduce the CPU overhead of the animation.
But I run my Test project on Android. It just reduces a little bit CPU Time.

Here is my test case.
I have a character with Face and Body Animation.
And these two animations will not control the same bones.
1. 1 Animators, 2 Layers which separates Face and Body, and I use Avatar Mask to mask the whole Face.
playing the face and body animation at the same time.
2. 1 Animators, 2 Layers, Face Layer weight = 0
3. 2 Animators control Face and Body separately, and I disable the Face animator.
These 3 cases do the same thing which is only playing body animation.

So the best performance I get is No.3. And the worst is Avatar Mask
(I get the data from profile UpdateAnimationBegin + UpdateAnimationEnd)
In my assumption, I thought using Avatar Mask can make animator ignore those mask bone.
But in fact, using Avatar Mask only affect a little bit on the CPU performance.

Is my test case wrong?
Or should I just use 2 Animator control face and body separately?

Thanks, Suzu
