I haven't used treadmill much in the past, but have started using one during the winter. One really annoying bug is with the "Calibrate and Save" function of the treadmill activity. It's great that you can input the actual distance ran after your activity, but it doesn't fix your pace plots, max speed, or even timing for your records. All of the information about the activity in Connect is basically useless. And this unfortunately carries over to other platforms like Strava via connections. It's very frustrating and seems to be a long time issue in the treadmill and indoor running activity for several years. At a bare minimum the pace should be scaled based on the new calibrated stride length. Ideally you could add manual laps and correct lap distance in Connect so the each lap can be rescaled. I would love to be able to hit the lap button every mile and have the watch or app scale each "lap".
