I was wondering about that as well! I noticed a few weeks back where this was showing additional or different data to what my S9 machine & ResScan software were showing. Then it stopped and was mirroring the main data across all three feedback systems like it has been since April. Three days ago, happened again for one day's reading. Not sure what to make of this. I'm on a Mac computer, so we can rule out SOME OF IT being an O/S issue.
PaytonA - I did get this once in a while but now that I wait a good 2 minutes after shut off before removing SD I have not had it happen to me.
In my case the machine was superimposing a session I did not have over the top of a session I did have. Some of the times gained or lost an hour of fictitious or real data in the bargain.
