Going back awhile...

My problem was not that you had to play the level again (it doesn't take long to get to the wrong-choise terminal, so I hadn't played most of the level) but that I didn't really understand what happened at first, and so I made the wrong choice the second time around as well. I ended up playing the first "wrong" tangent twice.
Also, I only did 4 of the "wrong" tangents. I think I accidentally did it right my first try in chapter 3 or 4. In the last chapter, I figured out the "wrong" and "right" choices and purposely made the wrong one.
