Fakour-90 and sedjil buff

Hello, i was looking on Fakour-90s and Sedjils on wikipedia, and i saw that Fakour’s speed Is 5M and sedjil’s speed Is 4-5M, why is it 4M in game. Both missiles have the same rocket engine, Its strongest engine in the game. So i would like to see Its speed in game and also put the Iranian F14 higher in br such as 12.7. I’m sorry for my english, im not native speaker:)
