The IAAF site announced the 'latest' rankings
http://www.iaaf.org/worldrankings/index.html
and looking over them I'm going to take back my previous criticism that they are 'ludicrous'. They are actually pretty close to T&FN. I did notice that the men's WC SP Champion is missing from the top 10 (#2 for T&FN), because he competed so little. A credible showing for the IAAF computer - certainly better than the BCS computer did!
