I don't have anything real special done to my Epic (yet) and just gave this quadrant deal a shot...got a score around 950 which is slightly higher than the average Galaxy S phone, or at least according to whatever the chart was. Nexus One 2.2+ was the highest at a little over 1,250 for reference. FWIW, I had 4G turned on when I ran the test, not sure if that would make a difference or not.
And I'm at work now, so I can't see the video linked above, so no, I haven't done whatever is suggested in that video as I don't know what it is!
