That's a good question, I just tested it myself. I have vip, and first hit on a tease was 274m without carepack , started a care pack and only got 494m..
It gets calculated like this when there is VIP and Care Pack. Ill use 400M as the base. Total Payout= (400M×.25)+(400M×2) Total Payout= (100M)+(800M) Total Payout= 900M So basically here is the formula -> Total Payout= [X×.25+(X×2)] I hope I helped!
