Dial in method

[Axis Racing]

As a newb to SS competition, are elemination rounds run like a bracket race with the exception of heads-up if both cars are from the same class?

In other words, the competitor chooses their dial in and can't run under it or a break-out occurs? Or is the dial-in chosen automatically based on qualifying times like some Quick-8 or 16 events use? I'd assume that qualifying sets your position on the ladder, and then it's a bracket race right? Otherwise I'd imaging that there would be way more CIC penalties with guys capable of running 1.0+ under...
