High Score Questions

As far as I can tell, AB is predictably random.  Structures are originally arranged somewhat loosely, allowing for the pieces to settle on their own each time there is a reset.  Sometimes this results in a self destructing level, other times it ends up making the structure more stable, and thus harder.  My personal theory is that the individual building blocks that make up each structure are also designed with a little bit of variability in their actual size and shape, adding just a bit more randomness.  Add in updates to physics models across different platforms over the years, and some levels get easier, while others get harder.  I have yet to find a level where the ABN average is out of reach, though in some cases it now requires days of endless flinging to achieve.
