A new test version should be available sometime on Monday through TestFlight.
One new feature is an Efficiency Bar graph which will display the last 32 samples. Each sample is taken at 1 km intervals. At the start of each drive the first factional km is discarded so it may take up to 1.9999 km before the first bar appears. The most recent sample appears on the right.
You can display in distance /kWh or Wh/distance. I recommend using Wh/Distance. You can switch between the two by swiping up or down.
The Clear button can be used to erase the oldest sample or if held down will clear all samples. You can only permanently clear when connected to the Leaf. If not connected the sample(s) will be cleared but will reappear when the app is started again.
The numeric value of the most recent sample is displayed at the top center and the range low to high of all samples is displayed bottom center.
Here is an example of what it looks like. I live on a bit of a hill so the drive out uses less energy then the drive back in this example.The very low reading of 1.6 Wh/mile is at the bottom after coming to a full stop so is offset with regen energy.
