    I think it's over-theorizing, since the user won't care about the rotations on the SSD. Users only look at data...

    Nadrek (8/19/2010)

    I'll simply agree with statements from two prior posts, slightly reworded:

    1) In practice, with normal humans using the data, NULL must have an explicit operational definition to be meaningful....

    Variables in algebra can be. That's what I thought, but if I have X and Y in two equations, it's not unknown. It's unsolved, perhaps, but...

    Redefining NULL on a whim? You can't redefine something that doesn't have a good definition to start with. N/A, unknown, not yet entered, incomplete, etc. can...
