Keep in mind though that even with this theory, you're at the mercy of the RNG, which has always been a cruel and merciless master.
The devs themselves say that there is no rhyme or reason to atma. If it makes people feel better to follow some kind of farming itinerary or ritual, there's nothing wrong with that, but RNG is 100% RNG unless there's a quirk in the system that even the dev team isn't aware of (unlikely).
