Well, the good news is that I don't drive on a piece of paper (or a computer screen). In reality, you only feel the dip around 4000-4500--which is a range I almost never use. Which is why I don't careAccording to the very graph you quoted the 'nice little low end torque bump' actually begins at 3200 RPM, bottoms out at 3800 RPM and doesnt achieve the same level or Torque until 4700 RPM.
So really you have to keep it below 3200 or above above 4700 to stay out of the power dip.
Here's a fake dyno chart that Subaru made. It's a representation of the changes for the 17+ model. It has a bit more low-end torque and they moved the low bump higher, so the dip is narrower on the newer cars.
