That's 100% right it's how I no I'm racing a novice who doesn't no what there doing and I tend to burn them while there on the transbrake of foot brake when they roll in and you put your first bulb on you have 20 seconds to put your second stage bulb on I always take my time and once you have been racing for a while you don't hear the car next to you because you are zoned in on that tree. It's pretty hard to explain but once you have done it long enough you will get used to just hearing your own car.
