Sorry, lots of new acronyms to learn...I am not getting anything like 204 miles and please forgive me but.... I have only owned the I Pace for 5 days, I am not physics savvy and don’t understand what you mean by SOC? Please enlighten me
SOC is state of charge, the battery level.
GOM is what we lovingly refer to as the Guess-O-Meter. It is the car's reported range, which as you learned, is not such a good prediction. Certainly while the car is new (or after a major update where the history might have been purged), the car has little information about your driving style or the car's average consumption to make a good prediction of range given the battery charge level. It improves as it learns bout your driving. The car, unfortunately, puts more emphasis on the range estimate instead of the SOC number. I imagine it is because they assume the range prediction will be close and that it is easier to work with than trying to do do the math of range estimation yourself while driving a car, but I'd like ot see both.
