    Exactly! COMPLETELY unimportant. The choice is not tough: do you want to give students instructions that are more accurate by at most a tenth of a minute of arc (which translates to even less than that for average altitudes), or give them instructions that are less prone to error and do not introduce a pointless extra step. If you're actually writing "practical" instructions, the first choice, going for a trivial improvement in accuracy, would be foolish, wouldn't it? If you are working on the last line at the bottom of a page, would you really want navigators turning to the next page to get that HP from the next line??
    Use the easy one line data lookup.
