Day to Night RT
Day to night delay box setting
Do you remove time? = slow down on reaction.
Add reaction time? = get faster on reaction.
Stay exactly the same? No change

And by how much. I am sure lighting of the tree comes into play. Assuming LED Bulbs being used which I think almost all tracks are anymore, maybe I am wrong.

With the old bulbs I use to subtract, now I add at night

So you are faster releasing on LED. Interesting. Ok thanks.

Most are slower at night and therefore take time out of the box.

That's what I thought, just had a limited sampling. Some say no change. A gentleman I know is pretty good says he is faster at night, but seems like MOST are slower. I don't box race a lot but at night I am about 0.015 slower than day.
Thanks

Luke Bogacki has spoken/written about RT variation day to dusk to night. Again, most are slower.

It depends on how well the tree is lit, but I’ll take out up to 20 numbers when it gets fully dark.

Takes some balls to do it if you were good the round prior.

Sun position before dark decides if I am faster or slower.

Day time to dusk (Sun starting to set but not fully gone) I usually pick up .010 roughly. Then can go back to day time or need to roll it out after sun is fully down. On some occasions, when sun goes fully down I find not needing to take it out at all because by that time we're usually hot lapping and adrenaline is pumping so lights tend to stay better if you stay focused enough.

Hook up a practice tree to your trans brake button and try it in your garage or trailer....

Daylight or lights all on and than in the dark...

See what happens.....I did that years ago....

I'm usually.010 slower at night. At the Million last year with Montgomery's spotlight on the tree I could not seem to pull enough. I thought I crushed it to be .020-.025.

Everywhere I have raced in last 5 years I believe so yes. But that is only 6 or so tracks.
I can't remember one that was still incandescent.
I'm sure there are somewhere
I just noticed going off bottom I was slower at night and wanted to ask what others experienced.

I believe I’m a deer in the headlights bottom bulb racing as well. I have amber interior lights and yellow fog lights trying to adjust to the sudden yellow blast when the tree starts. If I think it helps, it probably helps…. Maybe..

Eye condition, age and normal reaction all play a role. My son slows down as the sky darkens, I speed up and I'm 25 years older. So he's rolling out numbers while I putting them in.

Not to high-jack the thread but we have an east/west track and as we rotate the big star in the sky will sit right behind the tree. I have requested and maybe others a temporary blackboard behind the tree but they refuse. There are times when I can't even see the stage bulbs.
