Do you see results in the BigFix Console for the Analysis Application Usage Statistics for the computers in question? Is the Analysis activated?
I suggest that you run the Software Installations report again, and add the following two columns from the Application Usage section of the Configure View dialog:
- Last Used
- Average Run time
This may give you more insight into the numbers.
By the way, in your screen shot, the value 0.026 is actually Average Runs per Day.
