By the way, here is a link to an on-line calculator I've created for altitude corrections to 400m races:
http://desert.jsd.claremont.edu/~newt/track/wind/400alt.html It technically only works for world class times, so don't try to correct 47s or 53s races and assume it to be accurate for those. However, you can see the theoretical "1/2-second rule" coming out (in conflict with the experimental "1-second rule"). =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Dr. Jonas R. Mureika W. M.
