Fair point, some people here don't understand that flying a plane is not like driving a car
May I also stress on the concept of IAS? Let's remember that what reads on the speedometer in your cockpit is not your speed relative to the ground, but to the air that you're moving into.
The whole speed malarkey is a useless point of argument I think, there are not many gross mistakes with it and a 10mph error is not the kind of edge that makes the difference in a dogfight..
