I said it worked .... BUT ONLY if you time it with JST. Since it is the jap people who found this theory, so it is their local time ie "JST" instead our our local time, whatever that might be. So for those who called BS on this theory, you could be using your own local time. I tried farming mine for 2 hours using my own local time which is PST and 0 drop and as soon as i did some math and tried it with JST. Two atma within 30 minute at their respective hour.

That or the theory is total BS and i am just having lucky streak. Still could be RNG
