Speed and strength CAPS are not related to BMI. However, BMI can limit speed or strength regardless of their cap. A player can cap at 20 speed and 20 strength, but his BMI will limit how much of that speed and strength he can use in the game. Of course, none of this matters until the new engine comes into effect, and maybe not even then. There's still been no confirmation from admins that the current BMI system will be used in V.3 engine.
