About how much Originium can you save in a month?

I suddenly got curious and decided to do some calculations! I'm basing this on a month, and for weekly activities, I've calculated it over 4 weeks. The monthly subscription is included as a baseline! Attendance - 600 (1 pull) Monthly Card - 6000 + 1080 (6 Originium) (Monthly subscription) Daily Missions - 3000 Weekly Missions - 2000 Annihilation - 7200 Certificate 1st Tier - 1800 (2 tickets + 600 Originium) Certificate 2nd Tier - 1200 (2 tickets) Headhunting Permits - 22200 (Assuming all 37 tickets are exchanged) Total Originium: 45080 That's roughly 75 pulls! I knew Arknights was good for saving currency... but seeing it laid out like this, they really give out a lot! And if you consider the currency from events, it'll increase even more, right? Personally, I feel like Arknights also has the best gacha rates for the highest rarity, which makes it seem even better! Though the pity system is tough...
