When traveling on a long road trip, here is what I do. I charge to 100% right before I'm about to leave the house (leaving the battery charged at 100% overnight is not good for the battery so you want to leave the house as soon as possible). Then, I stop to charge when I'm down to around 20% or less. In about 20-30 minutes, you should have 200+ miles of range added. You could charge to 100%, but the ability of the car to charge from 80% to 100% is very slow (purposely done by Tesla to preserve and protect the longevity of the battery), so it is more efficient to just charge to 80% and to travel on until you are down to 20% or less and then charge again.
So, yes the reporter may technically be correct, but practically, no one does that, nor do they have reason to do that.
