Range update

So, I probably have a good 10 months of driving on the car and the battery pack is broken in quite well. The SOC gauge has been showing over 100% in the morning for a few months, but now it seems pegged. I was estimating the old fully charged SOC at 110% but now I'd say it's 120%. After I drive the 4.5 miles to work and she sits a few hours it shows 100% SOC. When I return home and let her sit, it now shows 70% remaining. These are highway miles too, at 60+ MPH...
Back in June I did a test and put 17 highway miles on a full charge. Now I could probably do 20 or 25. Maybe I should revise the range up a bit?
