The weight issue of F4EJ in Japan, American F4S, and British F4J (UK) housing allocation

Is it unfair for Japanese F4EJ, American F4S, and British F4J (UK) to have the same mount, but set the weight of Japanese F4EJ to 11.0? Should we increase the weight of Japanese F4EJ or lower the weight of American F4S and British F4J (UK)?

F4EJ has a worse radar and worse missile
EJ的雷达没有多普勒模式,导弹也是延迟长的AIM7E,所以它11.0是合理的
