At last I finished Math final exam last Friday. You know, I have been having hard time to catch up the Math classes because I didn't study Math in high school. Nevertheless, thanks to some friends who helped me both online and offline, I could manage to finish the class with (hopefully) a good grade :) Anyway, that's the background of how this formula was born. I felt like celebrating my successful Math career somehow. haha. Well, of course this one is neither proven nor precise. However, it does reflect my hypothesis about improving Go skills.  
I hope you have fun seeing this!
