JMO! If you do away with the head-up runs then it nothing but another bracket class. Why have it?

I don't think it's anything like a bracket race?
They don't have a breakout rule?
(they get docked on their index if they go to fast)

So, if you're faster than what you are dialed in at, you hope your opponent isn't faster than his dial in difference.

It's just more 'thinking' one has to do.

John,
I am going to have to look that up. That was not my understanding of how it worked.

From 2020 NHRA Rule Book:

HANDICAPPING

Comp, Super Stock, and Stock handicapping is based upon the NHRA index system. Handicap margins can be determined simply by comparing individual class index elapsed-time factors (as listed on NHRARacer.com).



DIALING UNDER THE INDEX
Contestants in Super Stock and Stock have the option of dialing under their class’ assigned index. It is the responsibility of each contestant to place the selected time on the windshield and tower-side window prior to each round of competition. Dial-unders may be changed between rounds, including a rerun situation. All contestants not choosing to dial under will automatically be handicapped on the basis of their assigned class index. In cases where two cars of the same class are paired, the race is conducted on a heads-up basis, regardless of any dialing-under considerations, and breakout rulings do not apply.

Later on it's written for breakouts:

BREAKOUT RULES
In Super Stock, Stock, Super Comp, Super Gas, Super Street, Top Dragster, and Top Sportsman categories, the breakout rules are enforced at national, divisional, and National Open events as follows: Contestants who race below the posted index or category standard during eliminations are disqualified, with the following exceptions: 1. when an opponent foul starts or crosses a boundary line 2. on a single run 3. when both drivers run under their index, the driver who is the least under is the winner 4. when two cars of the same class race (doesn’t apply to Super categories) 5. if two contestants run under by the same margin (with elapsed times extended to a thousandth of a second), the driver crossing the finish line first is the winner
