A lot depends on the weather, state of tune, driver abilities, it's an automatic, vehicle weight, etc. etc.
I suppose I always guess a bit low, then if I'm wrong and they run faster they are a lot happier and have something to razz me about when they run it and come back to the forums.
But, if they run slower they come back dissapointed, dejected and down in the dumps. I'd much rather not get their hopes up too high at the beginning and have them come back happy.
