Agreed. It would be great to know which parameters are straight reported values and which are calculated.Jaguar does some funny stuff with their kWh estimates. I routinely get 85kWh at 100% from WattCat (JLR API) when the OBD estimate is more like 80 or 81kWh.
That said, kWhs track very nicely with SoC. So I suspect the kWh value may be based on an assumed value.
