I remember and old post about making NU1 conventions achievable. The last two I know of have succeeded on NU1. The first I don't know details. I lucked into the last 5 min of it (just enough time to get a show and credit for the convention). The one that is about to wrap up was 1 hour and needed 3.75mil started at 2am server. Finished 4.5+mil.
2 for 2 this time around. Looking good balance wise so far.
