The monthly challenge is the global average of all the referrals brought in by all Pinkoi advocates. It changes each month, based on the previous month's average. We also have a top advocate challenge, this is the number set by the advocate who brought in the most referrals in one month. (This challenge might not change every month.)
When a person meets the monthly challenge, we give that person a 25% increase in bonus points based on the set value. For example, if the monthly challenge is set to 12, and an advocate brings in 12 friends in that month, we'll increase their bonus points by 25% for 12 referrals. So instead of 36,000 bonus points, the advocate will receive 45,000 bonus points.
