First off, I have made an index of the three teams performances over the past five years, with 1 January 2005 being 100.
Still Australia beat the pants off the other two still, holding a commanding +10 margin over India and South Africa.
But, as Fred the commenter mentioned yesterday, perhaps this overstates their performances for the last two years. So, here’s the same graph, with the index starting on 1 January 2008.
Interestingly, since May 2009 South Africa have been in relative decline, whereas India have been unmoved since then, saved for a slight increase in the past few months. By my calculations, this means that they are about tied with South Africa, by the ICC’s reckoning, India are the undisputed champions of the world!!11!!1!!
What this means for online sports betting is anyone's guess.
