I suspect becoming comfortable with Hub Station docking will always be one of the core achievements. When you have a slot that is wide and narrow that you have to pilot a ship through, botching said docking attempt can be a fatal error. You botch a docking attempt with a Clipper, Python, or even worse Anaconda and your bank account is going to have one very bad day. Thinking on it, I think the idea of having a docking computer occupying an internal, or utility slot, whichever, is a good thing. You have to pay for convenience. If you're in a sidewinder, hauler, adder, even a viper, it's really not needed. I've taken all of those ships in without even matching rotation. You get most of the bigger ships and if you don't know how to dock, you are going to pay, one way or the other.
