Power Match with new Rally pedals

I recently purchased new power pedals (Garmin Rally). When completing the first few workouts on TR there is a noticeable gap between the target IF and actual like a 0.86 target IF and a 0.79 actual IF. I use a Wahoo KickR in ERG mode. There was never more than a 1 point gap with my old (now broken) power pedals. I calibrate the pedals before each session and have power match turned on. Any suggestions?

Drivetrain losses? My Rally Pedals (and Vector 3s before) have always read slightly than my Tacx Neo 2T. As long as both are consistent, it doesn’t concern me.
