Sure, we use the lightning. What do you want to know?

First you run without any delay. Then if you find you're red lighting, just add some time in the delay and it'll back you off. In our case, we've typically got .020 in the box, since the driver is pretty consistently .010-.015 red without any delay. If it's a big race, and adrenaline is an issue, we'll bump it to .030.

Of course, your mileage may vary.
