"The ranks go from 80k to 200K, a big jump. In April her monthly sales were about 130k"
The Le-Vel rewards plan:

If I understand their lingo correctly, SW would have earned 20% on her direct sales, 12% on her level 1 customers and 4% on level 2 & 3 customers.
There are also Uni-level team commissions. SW was 80K VIP sales (monthly), so she would have earned 4% for 8 levels down.
There are other bonuses as well like "Infinity fast start", auto bonuses, all inclusive trips, etc.
I'll bet CW's sales were mainly from SW's effort and they did so to maximize their overall family income because they would be essentially doubling their downline commission to a point. JMO
