That's not as easy as it sounds either. There's alot that goes into making a decent run at the track. You really have to put alot of runs in to get consistant results. I for one am a crappy driver and can't seem to get out of the hole decent so my timeslips generally suck. You have to have a decent launch. Then you have to know where your shift points are. Track conditions and weather, tire inflation, reaction time, all figure into it so you can have a powerful car and it might not show in your timeslips.
