Am using Lezyne Super Gps for 2years now and encountered no issues until I paired it with a pedal power meter. Found out that torque efficiency and pedalling smoothness data displayedon the Super GPS unit during ride are way off. But upon uploading to GPS root (lezyne web site) said metrics recorded look okay. In short, what is displayed is not consistent to what is recorded. Raised it to Lezyne and was advised to update my unit. They have made two updates already since I raised this issue but sadly, the error remains
