Great variance can exist, from one passage of the 12th Planet to another. In some cases, as has been recorded by Plato, the Earth in fact rotates in a different direction from its current rotation. There are many factors that influence rotation, and those that dominate the scene immediately after a shift will determine the direction of rotation. If the core of the Earth is highly confused after a pole shift, swirling about under the dictates of many influences so that the normal dominance of the core in determining rotation has been muted or silenced, then the rotation of the Earth can be dictated by its immediate surroundings. The direction of rotation tends to perpetuate itself, so if rotation starts in other than the normal direction, it may be slower and arguing with itself, so to speak. These rotations are slower than the 24 hour day that you are recording now. If rotation is in accordance with many influences, lining up so that the motion chases and then departs from these influences quickly, then rotation can be slightly faster than the 24 hour day that you are recording now.
