It's been a long time since this discussion, but I have the same issue (LabView 2015, SP1). The "outrageous" numbers in a given run are similar, e.g.
etc, close to each other but not necessarily equal. It also seems that these pop up either under "Sub VIs Time" or "Total Time".
I tried hitting "snapshot" after starting the profile and before running the vi, but this does not seem to eliminate these bizarre numbers.
Thanks for any insights,
