Probably because you're all over the place. They've answered each of your questions the six different ways you've asked it.
Then make your own conclusion. Worried about it? Do some math or don't do some math; use a rule of thumb; see what is inside the back of the van to use; do as you please unless you are installing a circuit for a fire pump or sensitive electronic equipment, as Don mentioned. There's no right answer, it's entirely up to you as the designer of the circuit. There's been occasions I've used 1A as my load for the math, and other times I've used 20A, it depends on your opinion of the conditions and what they want to pay for.
