To calculate the Thunderbolt Solo Winner, we take the average of three solos. These include two competed in the regular competition and the one performed in the Thunderbolt Solo section.

To keep this fair, we require soloists who have more than three solos to declare the ones from the competition to be used in the Thunderbolt calculation before the competition begins.

For more information, please see: Why do I have to declare my solo's if I have more than three?
