This just means they are subbing out simulation details for injected randomness, no? I thought this was a technique that was known to work in general. I.e. sin

This just means they are subbing out simulation details for injected randomness, no? I thought this was a technique that was known to work in general. I.e. since the combination of many random events is a bell curve if you just put a bell curve somewhere you don't understand something you can get good results.
