Looking at the docs closer, I don't believe what I did is correct anyway. I think the docs are telling me that you cannot program 3 as opposed to, you must program 3. We do not have a check for this, but we're not programming 3 in the failing case. Let's at least make sure this makes the test pass on your system (it does on mine). Then I'll come up with some more experiments.
