A common thing for trackday first timers to do is to try and move out the way expecting other riders to come past (lots will fly past just before the braking zone if you are on an SV) so will be tempted to look over your shoulder/distracting yourself looking if someone is coming.
If you start getting overtaken (and you will LOTS on an SV at Snetterton
) don't start trying to get out of people way expecting an overtake, if someone comes up your inside, sure don't slam the door, but take YOUR line and if people want to pass that is for them to find a way, not for you to move over. This is actually likely to cause problems.
Does that make sense?
