I forgot to add the tl;dr of >>412365673
sorry


the tl;dr is, there is a lot of drigting happening with IMU based tracker. Simply because they don't have the special awareness to realize that they haven't moved at all.
If something happens that introduces a movement of any kind (like shifting your weight from one foot to another) the tracker may "think" it should move.
This will turn into your avatars feet sliding around on the floor (this is the drift we talk about).
