Weird (Incorrect?) Slope Graph

The slope graph in Isaac doesn't make sense to me, and I don't know if it's incorrect, or if it's displaying something other than slope as I understand it. See the screen capture and attached ride - neither the sign or the magnitude of the slope match the actual grade of the hills at any point. For ...

Crr, CdA + calibration advice?

Hi, I've been using my PowerPod BLE for a few months now, and I'm still not sure if I have it calibrated correctly. I suspect that my configured Crr is too high, my CdA is too low, and that the fixed Cm is also too low. I've carefully performed an out and back calibration ride, the PowerPod is locat...
