If it was paired with the powertap wheels at the time (got the Duos because I wanted the ability to have more wheel variety but still have the G3s, so I'll use them), that would explain some funky results I was getting when Zwifting on rollers when my Garmin was saying my 20 minute average was ~10W less than what Zwift was saying.
