    By "significantly" I mean rocks in the bilge.

    Gary, I would be the last one to suggest that error should be ignored. However, I would argue that error should be addressed, as much as possible, before the construction of position lines, in a useful way that leads to more accurate LOPs. That will be more likely to avoid those rocks than somewhat useless worrying about not knowing where one is as a result of faulty LOPs.

    Only gross error will lead to a position well away from the position line that should represent it.
