If that's not what you're suggesting then that was not done in any commercially available EV in the US today. Even starting closer to the California border like El Centro and only making it to fringes of Houston like Katy is ~1330 miles, so ~665mi a leg. No generally available EV in the US has that range. So I take it you did a number of like 10-60% or whatever charge jaunts.
Even then though, if you were to sum up all of those shorter charging sessions you probably had to recharge your car a total of at least four charges energy-wise. If you get 300mi of range on a full.charge, 1,330 / 300 = 4.4333...
It’s more just that it really, really matters time-wise that the car is not charging up to full on any given stop, because that means the charging stops are significantly faster.
People who latch on to the idea of judging EVs on their time to get “fully”‘charged are going to get such a distorted idea that they will never believe current EVs could be a good option. But, they would be mistaken.
