  Is there any data that show the order of pilots was changed due to TBL being used?
   
  No, I don't want to know WHO, just IF.  :-)

      TBL - scores go back to the pilots as is... raw.  TBL is only factored once a round is finished and the results calculated.  With TBL scores are adjusted to the whole score and result in whole numbers.  Remember, the entire score isn't thrown out - just a maneuver score.  When a score is dropped then TBL is run on the entire set of scores again to recalculate the mean and std. deviation - it is an iterative process until all scores fall within the range that are calculated for the pilots/judges.
   
  TBL was used at the TOC for all years starting in 1999 onwards.  It has been used at the WC since 2001 (I think).
   
  Bottom line - the system works very well and in the end the correct order of finish is picked - which is what we want.  In all the years of scoring with TBL at the TOC I saw very few judges scores discarded which probably says more about the quality of judging than anything else.  I'd be very curious what the results have been at the F3A WC's since it was implemented.
   
  I would love to see TBL in use at the Nats for the Finals in both classes - we certainly have enough judges to support its use.
