It can be a pain but it definitely makes sense. Mistakes are always made in this game and they are far more likely to be made by newer owners. It is kind of like how if you take an accounting class they teach you how to do everything by hand. In the real world, if you were doing such work, there are programs that do that work for you. Nevertheless, it is good to learn how to do something so you can understand it and it will hopefully prevent errors in the future. I hope that makes sense.
