Hey, there's a major bug right now with corruptions 1 and 2. There's something about how you're calculating it that makes having matching levels much better than having different amounts. In fact, 2,3 is less disruptive for than 3,3 for me (if others are the same)
In the options (little gear at the top-right corner of the screen), click "Controls" and you'll see bindings for Slow Motion and Fast Forward.
