Sniff & Capt Pit Bull,
As has been said below, do what the book says unless we, as we will always invariably try to do, cancel any in/out speed restriction to help you. It is a major teaching point and operational tool in the London TMA. On the other hand do not take the p*$$ with us, it will not get you anywhere. Please remember that we have a much wider picture than you think we might have.
