Thanks Nick.
I just wanted to point out one other thing in case I haven’t been clear (or have been mistunderstood)- Craig and others running very fast (regardless of race) are outliers. If you understand population dynamics you know that it is inappropriate to make make assumptions about an outliers performance based on the global population (of an ethnic group)….so there’s really no reason Craig couldn’t run sub 9.9 and I hope he does. But when / if he or another athlete of an ethnicity other than West African does, it still won’t make any real dent in the stats based conclusions I have presented about the populations as a whole.
RE: Indian & Asian…I actually agree with you that they are potentially sleeping giants in the athletic world.
