To phrase it more carefully: there are some very large projects that combine many maps and connections between them.
These have run times in the order of thousands of hours of CPU time and are beyond the reach of most experimenters in the field. I do not have ready access to the technology to experiment with these concepts is any meaningful way. The people that I know that do similar experiments are not able to build these large models and experiment with the model properties to learn how they work.
See:
That said, even with these massive resources the model is at the level of a single event of a single ball passing behind a post.
Where do I get 3 orders of magnitude? to be something I can do as a private experimenter I need to get from thousands of hours of CPU time to tens of hours for any practical experiments.
