This way, it will be clear where the 520 number that you use in your later calculations is coming from. Making notes like this and avoiding having numbers in your code whose significance isn't immediately obvious will save you and/or your coworkers time when reading back through a project.

I'm bad about not commenting in my code, and is a habit I really need to form.
