Well done Paul, I can probable guess which corners you are referring too
yes they are obvious.
Turn 1 is just a lift on turn in. The issue my line puts me on the standing water on the exit which makes me slower onto the power.
Church it means that I am running out of road on the exit and again there is standing water.
School is flat but Ian turns in later and so is straight up the hill to rocket and so stays on full throttle for longer. I am still turning at the clipping point so have to brake while turning.
Church and School is where I am loosing the time. I lift less than Ian on turn 1 so am quicker in but slower out.
