In a different thread someone was saying current shunt variation was affecting their HFI performance. Presumably they weren't able to get an accurate current measurement and this prevented an accurate inductance measurement?
Would imbalances in motor inductance due to super cheap motors have the same effect? As I understand it the detection is somewhat like a quadrature encoder measuring two inductances, so would it be possible to just have the user spin the wheel a few times, track the range of inductances seen recently, and detect a separate scaling scaling factor and offset for D and Q? Or is this already done somehow?
