I respectfully disagree Jacobs, at least in part. If a kid of 11 has only average velocity, then yes, it probably doesn't mean very much. But if a kid has really special velocity, as the OP says he does, then it means one of three things is likely:
1 - he'll have outstanding velocity at 16, just like you do.
2 - he'll peak at 12 and be an average or below average pitcher by the time he is your age.
3 - his great stuff will inspire travel team coaches to pitch the hell out his arm, and he'll be recovering from major arm or shoulder surgery by the time he's your age.
