Let $G$ be the number of Google hits of "guts round" at 10:31PM on October 31, 2011. Let $B$ be the number of Bing hits of "guts round" at the same time. Determine $B / G$. Your score will be

$$\max \left(0,\left\lfloor 20\left(1-\frac{20|a-k|}{k}\right)\right\rfloor\right),$$

where $k$ is the actual answer and $a$ is your answer.
