Every software update appears to increase the GOM range predictions because one's recent driving history is erased and a "default" range is reported. After a bit of driving, the GOM seems to revert to previous behavior. That doesn't mean that the November 2015 update didn't tweak the GOM algorithm resulting in higher range estimates, but I haven't noticed any change with our BEV.
