Spectra precision to Carlson's/SurvNet

We exported a raw file from a Spectra Precision Data Collector and brought it into Carlson for editing and processing. There were a lot of duplicate lines for control as if we shot them twice during the setup, once at the beginning and once a the end. I noticed that the data was exactly the same as the "first" shot on the control. The last line of data for the point ahead never happened. SurvNet thinks we have more redundancy that we do. I wonder how much more has been changed that I haven't caught? Anyone else have this problem?
