See the video and you will see the route. Its not level at all and measuring points are on the highs and lows of the route. So points during tests cannot give straight line results.

Points follow each other nicely from start to finish, meaning they dont change places (they move little but not much).

you always need to sum the A + B results for each run to get the wind effect. On diesel car testing there were huge differences how well car perfomed to more uphill or downhill direction. Thats why I dont test anymore in level roads as it gives you just how well it performs on that level road. The cars ecu program needs to perform well in all driving conditions.

When the values change you will get more resolution to your results. Same like putting your fans and ligths on for the same route. I have done that with diesel cars to get more resolution in some tests.

If there is wind (tuulta) 15km/h tailwind will give you little bit better results to wind direction the 2,0 bar measurement as real speed is 85 km/h (about 11.9 kwh on level road), but on the other direction speed is 115km/h which gives much higher consumption (about 21,0kwh )increase than the other direction has given lower. So overall is higher.

Its true more measurements should be done and I usually do them after more mods have been done to see if car behaves better. Also I learn all the time how this car behaves so I can estimate things better what effects what like the outside temp changes.
