I see that my original thread was moved to Homework. I hope it wasn't under the assumption that it was homework. I wasn't asking if I was correct, I was asking if I was the first person to calculate it this way. That I could not assume. I am not a history student, I am a C++ coder. School really isn't possible in all situations. I am working hard at understanding this just by thought. Edited: Pre-coffee comments removed.
