 All numbers are in Seconds or in Miles per Hour |
A. Dial
In: In a bracket race, you guess what time your car will run (without
going faster). EX: If I have been running between 13.50 and 13.55 all
night, I would probably dial-in a 13.50. This does not matter unless you
are in a bracket. B. Reaction Time: (R/T) This is the time between the last yellow light and when your car trips the lights at the starting line. Normally there are exactly .500 seconds between the last yellow and the green light, making .500 a perfect light. On a "Pro Tree" there are .400 seconds between the last yellow and green. If you trip the lights early (.499 or sooner), it is called a "Red Light" and you are automatically disqualified in a race. Very important in Bracket Races. C. 60 foot time: The elapsed time (ET) in the first 60 feet of the track. This number tells you how well you are accelerating off the starting line. Most people use it to determine if the car is hooking or spinning tires at the starting line. It is a factor of power and traction. D. 330 foot time: ET of the the first 330 feet. E. 1/8 mile ET: ET at the 660 foot mark. F. 1/8 mile MPH: The top speed attained during the run at the 660 foot mark. Also called 1/8 mile "trap speed." G.1000 foot time: ET at the 1000 foot mark (not usually significant) H. 1000 foot MPH: Speed at the 1000 foot mark. (Rarely used) I. 1/4 mile ET: ET of the 1/4 mile (1320 feet) J. 1/4 mile MPH: Trap Speed at the end of the 1320 foot track. K. Finish Margin: Used in a bracket race or heads up race. This combines the Reaction Time (R/T) and 1/4 mile ET (or 1/8 mile ET) and compares it with your competitor's. EX: (BRACKET RACE) Your Dial-In is a 14.500. If you ran a .538 R/T and 14.501 ET, your total time would be 14.539 (ET plus R/T over .500). Your opponent dialed a 13.000. He ran a .557 R/T and 13.201 ET. His total time was 13.258. Your finish margin is .039 and his is .258 so you would win because you are closer to your dial-in time. EX: (HEADS-UP) Add the R/T to the 1/4 mile ET. Whoever has the lower time wins. |
