Be aware there is also a setting in the instrument cluster for rate of charge, you can set it to Maximum or some lower value. A lower value will limit the charge rate regardless of what is set on the included charger.
GOM Range: This goes off the "since reset" miles per kWh reading (not the "since start"). So if you did not reset that, the number will not change. Reset from new it shows about 82 miles range. My driving style (not conservative) brings the GOM down to about 65 miles at 100% charge, meaning about 2.3 m/kWh. I have had it up to 2.8 m/kWh for a high-80's range. The terrain here doesn't lend itself to more than 3 m/kWh long-term.
