If the class allows it don't matter how you do it, beat me is key. We had a one off money heads up race back in the 80's rare for Santa Pod, got in the final and my competitor asked me not to use the N to make it a fair race. This was my 340 Cuda against his 440 Cuda, I thought about it for 2 secs only, why should I give up £250 which was a lot of money then, I'm not going to be the nice guy this time, but I did back off near the stripe some to make it look like a closer race.
