It's not always successful (since there are many possible aerodynamic solutions for a given set of parameters) and it's generally not too accurate unless it's been iteratively fine-tuned by the author to match the performance of the real-life aircraft. | ||

In the end, it really doesn't matter which one you use --- just pick one and use it. It's not a life-or-death decision. | In the end, it really doesn't matter which one you use --- just pick one and use it. It's not a life-or-death decision. | ||
