$$\begin{array} { | c | c | c | c | c | } \hline & \text { Stare 1 } & \text { Stare 2 } & \text { Stare 3 } & \text { Stare 4 } \\\hline \text { Day 1 } & 36 & 12 & 25 & 30 \\\hline \text { Day 2 } & 42 & 22 & 51 & 36 \\\hline \text { Day 3 } & 39 & 33 & 40 & 28 \\\hline \text { Day 4 } & 25 & 30 & 42 & 46 \\\hline \text { Day 5 } & 47 & 34 & 26 & 35 \\\hline\end{array}$$
