This is very rough. :)

Overall idea:
Provide a queue of previous runs that allows you to select one or more of the runs to affect the display of the results. When 2 or more runs are selected colorize the numbers that have changed, red for numbers that have gotten worse and green for numbers that have improved.
Control Additions/Changes:
- Run Queue - Displayed to the right of the test input field in the included graphic. Includes the ability to delete individual runs and select one or more runs.
- Clear Results button drop down - Adds the ability to clear the run queue.
- Results Pane - Improved results are colored green, worsened results are colored red.
- Colored results hover (Not included in mockup) - When hovering over a colored number in the results pane, display a tool-tip style pop up that lists the results for all of the selected runs in the queue.
