When I try to increase the N from 1000 to 100,000; The plot changes dramatically, which it should not. Did I miss anything ? Thanks

The time course changes because by default, you always start with 1 infected individual. If you start with 1 out of 100,000 it takes a lot longer to reach a peak than if you start with 1 out of 1,000 infected. This is expected behavior. If you're talking about something else, please clarify. Thanks!

@aquaxi Just in case you're referring to the Python code in the notebook, b needs to be normalized by the population N.
