Question : Problem: What can I interpret from the carrier busy signal test?

I have the following output from the signal carrier busy test on my AP.

I take it the lowest numbers mean the cleanest channels, so from the following output am I looking at ch 7 2442 being the cleanest channel, even though my ap auto scans to channel 10
