<DIV>RE: I would love to know how you determine a pilot bias based on
score sheets?</DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>There is information to be gleaned from score
sheet data. Just how you use it and how much faith you have in it is up to
you.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have conducted many judging seminars on
Saturday evenings at contests. I scored those same contests. I judged at some
of them. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>ALWAYS the judging on Sunday is tighter (two
judges scores track closer together) than on Saturday. I have felt that the
Judging Seminar tended to make the Judging more consistent. I hope it is
consistently better, but without getting scientific about things, I cannot be
certain. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I can also see that my judging is too sympathetic
toward all the pilots. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have not scored the Nats since 2000 but I
recall that there are many instances where the judges will track within 1-1/2
point of the mean for all judges for a round.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>You cannot make any hard & fast calls on what
these numbers mean but they tend to indicate system faults.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>BTW, I think any maneuver that produces a big
variation in judge's scores should be eliminated on the grounds that fair
judging of that maneuver is unlikely. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>There are ways that the scoring system can be
redesigned to factor out any malicious scores. One way would be to change any
score that is more than some distance (2 points?) from the median to the
median. That would have the unintended consequence of "tightening up" the
rounds scores. Probably not much of a solution. </FONT></DIV>
<DIV><FONT face=Arial size=2> </FONT></DIV>
<DIV><FONT face=Arial color=#0000ff size=2><STRONG>The issue</STRONG>
<STRONG>I have with that approach is it waters down the occasions when the
judge that issued a zero was the correct judge. Not catching the top hat
not being inverted comes to mind as easy example. Rolling wrong way on rolling
maneuver is another. Why do the number crunchers they are more correct
in raising the bad number when the more accurate somtimes is to issue another
zero? </STRONG></FONT></DIV>

<DIV><FONT face=Arial size=2> Del</FONT> </DIV>
<DIV><FONT face=Arial size=2>Try to keep in mind the ideal condition is to
have only one judge that is perfect in every way...</FONT></DIV>
