-The scaling of the number of iterations is tested in \texttt{src/project2/scaling\_tester.cpp}. The results are shown in \autoref{fig:scaling}. On the logarithmic scale, we see a trend that is roughly of the order $\sqrt{\log N}$.

+The scaling of the number of iterations is tested in \texttt{src/project2/scaling\_tester.cpp}. The results are shown in \autoref{fig:scaling}. On the double logarithmic scale, the scaling is approximately linear, indicating a polynomial relation between the number of iterations and the matrix size $N$.
