Perhaps it is, but also when modeling, there is often more than one way of doing things, and remembering all the tips and tricks out there can be challenging. When it comes to modeling, you use it or lose it. I think this is why this platform is great: it is a good way to keep practicing and staying in the loop. And having people with a lot of experience (like you) that can pinpoint pros and cons of different approaches is a real bonus. | |

Original problem was maximization, so we negate the objective.
