Live National Trails Raceway - Page 4

Looking at the results, I am baffled at the Accutime reaction times. I remember way back when chrondek (?) gave a figure that you had to subtract a constant from to get the actual number - like a .443 was actually a .043.

Some of those numbers make sense if you drop the last digit, but most of them don't, unless it makes sense to think that people going rounds are cutting 600 and 700 lights.

Anybody know how that system works?

I was there and I have no idea. Every time I went down the track, the live feed speed numbers in my lane would be wrong. Said I went like 113mph every time but I don't think I ever eclipsed 100.

.443 on a four tenths tree would be actual .043. On a five tenths tree .543 would be actual .043. Would depend on class.

That blinking blue light between the stage lights drove me nuts. I prematurely stopped every time, or at least most of the time it popped on. They need to shut that off. What's it for anyway?

I believe that the flashing blue light means the system is ready for you to stage

I just googled IHRA Stock indexes and the ones that came up are the same as the current NHRA indexes?
