Balanced leg rule: Your power leg is the direct with the highest total team business. Other directs means all your remaining directs combined. For each milestone, each side must reach the full target in new business since your last reward — for example, Star Achiever needs $2,500 new from the power leg and $2,500 new from all other directs. When both sides qualify, the reward unlocks.
Time limit: the days for each reward are counted from your first top-up. Reach a milestone within its day-limit for the full cash — if the days finish, the cash is halved to 50%.
