Stuart.W,
I meant that if you put a stopwatch in your car to time your lap you'd be a twat, as to do so would imcriminate you in the event of an accident.
If you want to play the hero with your claimed sub 10 minute lap, go ahead. i'm not saying that you didn't do it (from where to where on the circuit incidently, seeing as you can't actually normally do a full lap), but i'm not bothered either way. as i said, i go often enough and have a great time everytime i go, regardless how long it takes to get around.
different weather conditions and traffic conditions makes comparing times pretty pointless anyway.
