When I'm QTing I chase the fastest ghost for the car I'm in. I set it with 0.3s lap with reset for each sector. I do NOT run my ghost. If I'm running faster, then my ghost overlaps, distracts me and then I invariably crash out. I figure I'll never catch the world's fastest ghost so that is okay to run close, but it is a sweet feeling for those times where you're keeping pace and even, occasionally, catch up. That's rare, but when it happens I know I'm on for a top 750 global time..
