TBL, as applied in F3A, is done at the flight level, not the maneuver level.  TBL will nullify the entire flight for the judge who is statistically higher or lower than the panel.  So a pilot’s average flight score for a round may be based on 3 or 4 judges rather than 5.
 
The problem with the missed zero is still a problem, but it shouldn’t be attributed to TBL.  When using “drop high/low” as done in the US F3A Nat’s the correct judge may very well be thrown out.  Check out the FAI full scale solution here:

The real problem with TBL is it assumes a very low score to be incorrect. A perfect example of thesis the last TOC. In the last unknown there was a maneuver with a 1 1/4 negative snap on a downline. Chip was flying and snapped the wrong direction, but being Chip, he snapped 1 3/4 turns, coming out on heading in the correct attitude, fooling all but 1 of the 10 judges, who correctly gave him a zero. That zero was nullified by TBL.
 
Bonus points if you know who the judge was...

The TBL method applies proven statistical probability theory to the judge's scores to resolve style differences and bias, and to avoid the inclusion of potential faulty judgements in contest results.
