I discussed the question with you and never used harsh words. You'd better clean your mouth before you open it.
Your example about sprinters really don't make any sense. Very contrary conclusion can be draw with your logic. Marathon only use second as the smallest unit, why should sprinter need millisecond?
Even if intelligence ability is manifold, aren't they highly correlated? Do the people vary in understanding maths, physics or your physiology?
Folk, you'd better think more besides your cacostomia.
