Update to "Top 50 CPU Growth - Last 30 Days" by @chrissmail (http://thwack.solarwinds.com/docs/DOC-103485).
Added average CPU percentage and created an Orion Report with field formatting. When you edit/save the report in Report Writer, it will warn/info about the NodeID not rendering correctly, but this does not seem to be an issue as I've run it successfully in Report Writer and the Orion web interface.
Further development could help detect trends with CPU changes (i.e. a given node that has positive change over multiple iterations). As it stands, I like what @chrissmail gathered and plan on reviewing it over the next couple months to observe performance changes.
