Het is denk ik vooral dat het voor leken allemaal maar subjectief lijkt.
Hier maar even een voorbeeld van bij de gymnastiek. De gemiddelde kijker heeft daar natuurlijk geen idee van:
Judging and score tabulation
Two panels of judges score every routine, evaluating different aspects of the performance. The final mark is the combined total of these two scores.
The D-score (or Difficulty score) evaluates the content of the exercise on three criteria: the Difficulty Value (DV), Composition Requirements (CR) and Connection Value (CV).
* DV: The difficulty value of the eight highest value elements of the routine, including the dismount, are added together. Elements are ranked depending on their difficulty; for example on beam, a back layout salto to two feet is given a difficulty of E, and a back layout salto with a full twist is given a difficulty of G. For a G skill a gymnast earns 0.7; for an E, he or she earns 0.5 points.
* CR: Gymnasts must demonstrate skills from five required Element Groups on each apparatus. A gymnast may use skills to fulfill the DV and the CR simultaneously. For each CR presented, 0.5 points are awarded. A maximum score of 2.50 points may be earned here.
* CV: Additional points are given for connections of two or more elements of specific value, with 0.1 or 0.2 points apiece.
Although the A judging panel does not take deductions, they may decide not to give gymnasts DV or CR points for elements that are performed with falls. A gymnast may also lose CV credit if there are extra steps or pauses between skills that are meant to be connected.
The D-score is open-ended; in theory a gymnast could obtain unlimited points by performing connected skills although this was made harder in the 2009-2012 revision of the code when the number of elements that counted towards the D-score was lowered.
The E-score (or Execution score) evaluates the performance: the execution and artistry of the routine.
The base score is 10.0. Judges do not add to this, but rather, take away points for errors in form, artistry, execution, technique and routine composition. There is a 1.0 mark deduction for falling off an apparatus. Errors are judged to be small, medium or large and respective 0.1, 0.3 and 0.5 deductions are applied.
The D-score and E-score are added together for the gymnast's final mark.
This judging system applies to all WAG and MAG events except vault. Vault scoring is somewhat different:
Every vault has been assigned a specific points value in the Code. The D-score is simply this value. Every gymnast performing the same vault will receive the same number of points.
The E-score is the most important score on this apparatus. The judges on this panel work from the 10.0 base mark and deduct for form, technique, execution and landing.
As with other apparatus the D-score and E-score are added together for the gymnasts's final mark.
There are several acts that completely invalidate the vault and result in a score of 0. These include receiving spotting (assistance) from a coach, going before the signal and not using the U-shaped safety mat for Yurchenko-style vaults.[6][7]
