NCM Summary Reports and "As of Last Update"

Looking at the NCM Config summary page there are some default charts that show config comparison summary info, for example

Overall Running vs. Startup Conflicts

Overall Baseline vs Running Config Conflicts

I am not sure if these reports are accurate

I am seeing "As of Last Update" as one of the options

what exactly does As of Last Update mean?

I am trying to figure out how this works, since some of the nodes that show up in the conflicted baseline vs running config report, have the latest running config backed up and set to baseline
