3/3 Precision, 164 hit and your yellow attacks will never miss (dodge/parry is another discussion).
So what exactly is impacted by the chart above? Your OH whites almost exclusively (because your MH whites have been replaced by Heroic Strike). So you're looking at a ~19% chance to miss with your off-hand whites.
Considering the much larger top-end damage on your MH, which factors into your yellow attacks very signficantly, off-hand white damage is dwarfed (would Deep woulds be a bigger factor?). Factor in larger crits off MH Yellows and the gap between 1-hand and 2-hand TG damage would increase even more.
Miss #s aren't a big issue in a fury rotation as long as you're yellow capped. Adequate Exp and placement behind raid bosses (and lets face it, thats the only DPS anyone REALLY cares about) and you're a DPS machine.
