Short description of error
When I have a Bone Hierarchy above two bones the 3rd one moves the object as a Slow Parent.

Exact steps for others to reproduce the error
Add a Bone. In edit mode Duplicate it 2 times.
Set the Parent of Bone.002 to Bone.001 and the Bone.001 to Bone.
Add 3 vertex groups to the Cube, name them to the Bones and assign weight to 100%.
Add an armature modifier to the Cube and link it.

Try to move the Bone, it works okay.
Try to move the Bone.001, still okay.
Try to move the Bone.002, it moves like a Slow Parent.

It seems like a bug and I can't find info on this...

Event Timeline

I have tested this with 10 bones, and this behavior makes sense. Since any parent will move all child bones and all bones have influence on vertex position, moving ultimate parent node will have greatest influence and moving ultimate child least influence.

But this is just my guess, I know nothing about rigging...
