On average 3 Red Dice result in: 1.5 Hits, adding in either Focus or Target Lock it bumps up to 2.25 hits.
Accuracy Correct guarantees 2 Hits, making it statistically better than 3 Red Dice with no offensive buff, and a bit worse than 3 Dice with some focus.
In addition the guarantee of 2 hits means the x1 can focus on defensive actions (evade comes to mind).
Alternate options: for a single point you can put Advanced Targeting Computer which gives a guaranteed Crit if you maintain (and do not use) a TL. This is strictly better than 3 Red Dice as it is 3 Red Dice, except one roll is always a crit. While you can't spend a TL with this you can still spend focus (which is more or less equal to TL anyway).
What this really does is let you get a 20pt fighter with great survivability and good damage output.
