Tiers are assessed on a quarterly basis. The dates are as follows:
Q1 – Starts January 1st, ends March 31st
Q2 – Starts April 1st, ends June 30th
Q3 – Starts July 1st, ends September 30th
Q4 – Starts October 1st, ends December 31st
On the final day of each quarter, your model rank bracket and the number of days you were in that bracket will be recorded, and the number of qualifying uploads counted to determine which Tier you have earned. Your payouts for the following quarter will be calculated based on that Tier.
For example, the payout you will receive in May for April earnings will be calculated based on the Tier you earned in Q1.
