Dear fellow Garmin warriors,
I have recently purchased an Edge 530. I now test it with my Tacx Neo 2T along with Fenix 7 and TrainerRoad app on my Android phone (all three simultaneously recording my indoor cycling activity). I have now completed several rides and I have to say I am unhappy to discover different results from the same activity. I have found several topics regarding this issue, but I still have many questions regarding this unpleasant anomaly.
I receive Cadence, Speed and Power from Tacx Neo 2T and HR values from HRM Pro plus. All devices/sensors are updated to the latest software/firmware.
Please find below a summary of results:

1. I do not completely understand how can results vary when values are received from the same sensors and processed through Garmin Connect. As you can see there are some big differences (i.e. Training Load).
2. I understand even though there are now three activities in my GC only one is taken into account when calculating sums (Training Status, Readiness, Body Battery, vigorous minutes ...). However, which one is it? The first that is uploaded?
3. As you know you get several respective additional values from Edge and/or Fenix 7 (i.e.: Edge: Temperature; Fenix 7: Stamina). It is quite bad you cannot simply merge these activities into one and get everything from both devices. Any suggestions?
4. If you had to choose between Edge 530 and Fenix 7, which would you say to be more precise (based on your experiences and precision) and simply delete other activities that are duplicated? Remember, they both use same sensors.
5. How about outdoor comparison between Fenix 7 and Edge 530 for cycling activities (Road)? I have Rally RS100 for power and HRM Pro plus for HR. GPS from Fenix 7/Edge 530.
There is a ton of related discussions about this annoying issue, that should be addressed seriously by Garmin.
Please share your experiences and thoughts to help everyone with similar problems. Thank you and rock on!
