I'm still working on the post-beta payout model and stats (and have been working on some backend stuff in the meantime which delayed post-beta accounting). The beta period and offer still stand. Also, all data for post-beta model is collected and calculated since 2014-01-04 and the post-beta stats will include this period as well. I finally finished most of the urgent backend stuff that needed to be taken care of and I'm going to deliver post-beta stats very soon!
