It depends on the system that the track is useing.
some tracks perfect is .000 and a red light makes it -.xxx a negitive number.

some tracks perfect is .500 and .499 and lower is red.

my home track was .500 but they recently updated the system and now use .000 system. I still compare to the .500 lights. for example if I get a .020 light I say I had a .520 light when talking to others that have been racing there for I while.

Some tracks switched to the new LED light bulb system thus the .000. The eye picks up the lights faster on the new system. The old bulbs are on a .500 for us old guys.

our track switched to LEDs a while back but just recently switched to the .000 system. I think its still the same tree. I didn't noticed any differnce in the tree. even if its a .000 light its still a .500 tree or .400 if its a pro tree. The only thing they did was make a .500 light equal to .000
So old system .500 = new system .000
The .500 is a combination of the time it takes the driver to react DRT and the car to react VRT. They didn't change that. If you had to go .500 faster than before then your VRT would have to be .000 and your DRT would have to be .000 in order to get a perfect light

now switching from old bulbs to new LED ones was a differnt story. People were redding alot at first but it only took a few weeks to get everyone used to them. Basically everyone in footbrake just had to slow there VRT down by lowering Launch RPM or other things that slow down VRT

ya, they switched milan dragway from .500 to .000, now they go 4 digits, .0000


back when i was 16 in my first year of racing i pulled a perfect light (when it was .500) at high school national, and i got a perfect light when it became .000

now it have to try for 4 zeros for that perfect slip, funny thing is both my perfect lights were in my first year racing when i was 16, lol.

I still consider .000X a perfect light. I have only gotton one .0000 light. I have probley got about 15-20 .000 or .500 lights in the past 3 years but I race alot so I got a lot of chances at it . I had a win with a margin of victory once of .00004

What tracks are you running at? I have never seen a time slip that showed four or five decimal points. Post up a time slip.

They normally show 4 digits after the . but because that race could not have been a tie they had to show the 5th digit. If its that close they can keep going I am not sure how far they will go but I think its at least 8 if all the first 7 numbers are 0's.

I meant to scan that one that was so close but I lost it before I got a chance.

A few years ago I was at the track and we were discussing the light. I was originally under the impression that at this track a .500 was a perfect light, but then comparing my slips and others and the fact that we weren't getting red lights, we determined that it was indeed .000. So the very next run I pull a perfect light! Pretty funny I though.

They started using it at Gainesville Raceway in 2003, and I believe all the NHRA national event tracks use it now. Seems weird that I now say "I was double-o something" instead of "five-something" after it being .500 for soo many years!
