Minimal estimated pull income per month

Since this is an interesting question, I made a short calculation for that:

Dailies:
You get 200 Oroberyl from daily chores.
In a month (= 30 days) that makes:

200*30 = 6.000 Oroberyl

Monthly Card:
The monthly card also gives you 200 Oroberyl daily.

In a month that makes:

200 * 30 = 6.000 Oroberyl

Weeklies:
You get 1.800 Oroberyl from weeklies (tentatively).
A month has around 4 weeks, which makes:

1.800 * 4 = 7.200 Oroberyl

In total that makes in a month:
6.000 + 6.000 + 7.200 = 19.200 Oroberyl

Pull cost is 500 Oroberyl:

19.200 / 500 = 38,4

So, it means per month from dailies, weeklies and the monthly card you get 38,4 pulls (in CBT2), which means it takes about 3 months to hit the 120 guarantee.

It's still an estimation because to my knowledge, the amount of Oroberyl you get weekly is still uncertain.

(This calculation does not include Oroberyl gained from exploration, sidequests or the certification shop and other miscallenous stuff. So, it might be more.)
