Some considerations about the FM purists...

IMO performance is very important in the game because we don't have some other important variables like fear, fatigue, performance drop due to wear etc. So it makes a huge difference if a plane is 5km/h to fast because the other player will push his plane to the limit and not let you go away until he catches you. No worry about fuel limitations or possible death or physical body limitations.

That's why 5 km/h can make the difference
