In reviewing observations of binary stars taken with adaptive optics on the 3.5 m Starfire Optical Range telescope over the past two years, a quarter of these calibration binaries, taken from two Excel Spreadsheets offered at the 2011 AMOS conference were found to be off orbit. In order to understand such a high number of discrepant position angles and separations, all previous observations in the Washington Double Star Catalogue for a sample of five binaries were obtained from the Naval Observatory. Adding our observations to these yields new orbits for all. We have detected both components of Gem for the first time, and we have shown that 7 Cam is an optical pair, not physically bound.
