 \subsection{Sensitivity of Performance Clusters to Frequency Step Size}
 In this section we study the sensitivity of the performance clusters to number
 of frequency steps or frequency step sizes available in a given system. We computed performance clusters offline
-and analyzed the difference between clusters with coarse frequency steps and a clusters with more frequency steps.
+and analyzed the difference between clusters with coarse and fine frequency steps.% and a clusters with more frequency steps.
 
 Figure~\ref{sensitivity} plots performance clusters for \textit{gobmk} at
 inefficiency of 1.3 and cluster threshold of 1\%. We chose 1\%
