Okay, I get it. But it is actually pretty easy.
Below 10-15% at V3 gets you full speed.
At 50% you are down to 150 kW
Once you are at the Supercharger, all the info is essentially there.
Tesla tries to simplify things and making people think that the information is important, gets people confused.
While on the road, the navigation does the calculations for you, it tells you how long you will need to stop.
And hence my recommendation of when road tripping, run from 5% to 50% charge. The time you spend charging will be significantly less than if you go 20-80%. That's because 250kW never can kick in at 20-80%.
