I am experiencing recent supercharging projection underestimations for my 2015 MS90D. I only notice the variations miles after leaving the supercharger. Any help or feedback would be appreciated as a miscalculation such as this could leave an owner stranded. Here is additional information regarding one of many recent circumstances.

Issue
- When Supercharging, the estimate of a sufficient charge to reach the next destination has recently been significantly underestimated
- The estimated amount at the Supercharger is less than the amount of actual miles necessary
- Several miles into the trip the update is generated yielding the variation
