Range variation

[gm12]

Hey,
I did about 12,000 km on a recent trip from Sydney to Darwin and back, and never really felt I had a handle on what range my model 3 LR really had. I know head wind, and elevation make a difference, but to be honest my route was very flat, and I only really had bad head wind one day which I factored out.

So, here is a busy graph of my wh/km readings across the trip. The blue line is what the car consumed in wh/km. The other lines are possible reasons:
Red circles - exception circumstances
Black line - Average highway speed.
Green line - Vehicle load (extra weight)
Purple Line - Road construction.

As you can see, the only thing that fits the graph is a combination of road-type and speed. Does that make sense?

I also mapped outside temperature, and this doesnt seem to have any correlation because its mostly in the mild range of 10 to 35 degrees:

Speed (and any roof racks, towed object) plus wind = air resistance
Road type, rain = rolling resistance

the chip seal roads are a significant energy drain, also cool mornings when the pack require’s more heating and the cold road prevents the tyres Increasing pressure as fast as a mild morning.

I think incline is an important factor too, and less importantly, tire pressure.
If you have logged drives with TeslaFi/TeslaMate, you would be able to get much detailed information than what you have gathered so far.

Based on my data, chipseal roads are taking 10-20% of my range. But I cant find anything online where that's been measured more accurately.
