I could just wait until my referrals get their own referrals but some of them don't know how to do that, so those who know how to get refs help the team and those who don't just have to wait for spillovers. The team grows anyway, slower or faster. Some teams like the chinese team and the indian team are growing superfast because everyone is actively getting referrals, smaller teams like mine (cause i don't live in china or speak chinese) had to start slower. As the team grows the build down speed grows.
