Air Scales

To calculate the air score for a given trick, count the frames, then use the column that applies to the trick based on the chart above.

Note: Combos are an average of frames for each component. So if a rider does a 42 to 38 frame roll to roll combo, their air frames would be 40.

Weightings

For the Free ride and 3-trick events, the score for any given trick is calculated based upon the air, technical, and style components.

The weighting for each category is as follows:

Air

Technical

Style

1

.2

.1

 

To calculate the score for a given trick, multiply the air score times the air weighting for the division, multiply the technical score for the trick times the technical weighting for the division, and multiply the style score times the style weighting for the division. Add these three numbers together to get the total score for the trick.

Examples:

  1. A rider gets 46 frames on a wake front flip with a style score of 2. The Air Score (based on the A Air Scale) is 2.181, the technical score is an 8. So, the overall trick score is calculated as (2.181 * .1) + (8 * .2) + (2 * .1) = 2.181 + 1.6 + .2 = 3.981
  2. A Pro rider hitting a 45 frame Ball and Chain with a style score of 4 would score a 4.394 for air (using the C scale), so the trick score would be (4.394 * 1) + (40 * .2) + (4 * .1) = 4.394 + 8 + .4 = 12.794.
