Larry,
Previously I had been able to confirm that a "Rated Mile" varied from car to car, but at least on my car between 4.0 and 5.8 stayed constant. With 5.9 I was able to confirm that my "Rated Mile" was changed on my car by about 2%, but it appears that the "Ideal Mile" was left alone (at 265 Wh/mi). Furthermore 5.9 remapped the SOC displayed to users vs. the true battery pack voltage. This makes my "Rated Range" comparisons at full charge (Tesla's 100%, 4.15V per cell, etc.) under 5.9 about 2% incorrect, and up to ~10% incorrect at lower displayed SOC's. Using "Ideal" instead, full charge comparisons are correct, but lower SOC states will still show the remapping discrepancy.
Some of the graphs from my data are over in the Decreasing Mileage thread.

When on a long trip that requires this, (while not always going down to 0), the amount of energy used has decreased in lock step with my tracking of a full charge, dropping from just over 80kWh -> ~72kWh now.
