Most of my charging stops on this trip the battery was between 20-30%. The car charged around 75kWh to 50%, from there it was around 65kWh up to 70%, and then around 40kWh when I
If I can offer a suggestion to help you increase your overall trip speed:
Just as with NASCAR, "Splash and Dash" is the mantra for EV road trips. This means that the lower state of charge you can arrive at a charging station, the faster you'll get to your destination. You then only charge until you have enough to make it to another reasonable charger or as long as you are still charging at a high rate. Once your charging slows to some point, if you can make it to another charger, you might as well get back on the road and keep moving toward your destination.
Clearly, it takes experience and I don't know that other manufacturers offer the same convenient tools that Tesla offers to make this easy and more comfortable to do. The real-time Trip Energy graph (below) is particularly helpful since it shows how you are actually doing based on actual conditions (mostly affected by speed and wind) and how that will affect your state of charge at your destination.
Doing these calculations in your head while driving, knowing only your GoM ("Guess o Meter) range estimate, distance to destination, possibly with an elevation plot, while I've done them, is probably beyond many and definitely is not "easy driving" for anyone.
When you can, however, if you only charge enough to arrive at the next charger with less than ~10% SoC, you'll get much further, faster. It takes experience to do so without inducing too much anxiety, however, so I'm not suggesting you do this. But you can.
