As AF said, some new members get hit hard with pos rep early on and it boosts them up.
Rep is a lot stronger now than it was back then, because we've recently (like 5 months ago or something) updated the rep system to add many more ranks.
As such, higher repped people are repping lower members and they are getting way more of a push into green than older members ever had.
Can't really control it.
