TBLP

[Derek Koopowitz]

F3A uses TBL not TBLP - a subtle difference.  As an aside to this... If what
you wrote below is the case then in everyday Nats competition the judges are
being judged as well - we discard high/low scores.  What's the difference?

One other point - TBL (or TBLP) is NOT used in any AMA pattern event (to my
knowledge) so this point is moot.

A statement was made in this discussion group,  about the TBLP system not
being for ranking judges, but for scoring pilots.  I believe this statement
to be in error.
Either that, or I have misunderstood the meaning of the statement.
In actuality, it (Tarasov-Bauer-Long-Penteado) is used to determine which
judges may or may not fall outside a "window" of scoring.  It is used to
identify, in any given contest, those judges who are outside the "norm."  It
is explicitly stated* that "In case you judges are concerned this process
corrupts your rankings, when the scores are normalized in this manner to
remove stylistic differences between judges, THE RELATIVE STANDING OF EACH
PILOT IS NOT AFFECTED."  (sic)(Caps mine)  It further states that "in world
championships where ten (10) judges are used, it is not uncommon to see
three (3) or even four (4) judges deleted from a pilot's flight scores."  I
believe that these statements indicate that the judges are, in fact, the
ones being judged.
It is a fairly rigorous mathematical exercise and points out those judges
who may not be scoring contestants in a manner consistent with good judging
practices.
This book makes very interesting reading.  Underlying it all is that even
with the full size aircraft, and  world class competitors, in a sport many
years old, the participants and executives are still even now concerned with
judging.  And wisely so.
