I wonder what the words would be for precision, error, and tolerance. One word used in this context might be {DIch}, since the point is to make certain the measurement matches the actual quantity within a known margin of error. {Qagh} might not be the word for this type of error: why would being able to determine the distance to the target within 0.1 kellicams have any relationship to forgetting to seal the airlock?</div></div><div>~&#39;eD</div>-- <br><div class="gmail_signature">My modeling blog:          <a href="http://bellerophon-modeler.blogspot.com/"; target="_blank">http://bellerophon-modeler.blogspot.com/</a><br>My other modeling blog:  <a href="http://bellerophon.blog.com/"; target="_blank">http://bellerophon.blog.com/</a><br></div>
