I've been a mechanic for 12 years. We tell our customers the same thing after a complete motor rebuild. The reasioning behind the changing your speed is do to the cross hatching on the cylinder wall. With out getting to technical, if you did 1 rpm for too long on a fresh motor, it would/could smoke later in it's life, on decceleration. You really would have to stay at 1 rpm for hours to make it happen. If you take the advice of what the other guys said, you'll be just fine'

have a good trip!
