Cricket's one-day rankings can reshuffle overnight without a single ball bowled
Every May, cricket's one-day international table can change order while every team sits idle. Old results simply age out: the oldest year of matches vanishes and a more recent year drops to half weight. A side can wake up a place lower without having played, purely because a good season from three years back has expired.
The International Cricket Council's system works a lot like a batting average. After each match both teams bank points, and a team's rating is its points divided by the matches it has played. A win always earns more than your current rating, so the number climbs; a loss always earns less, so it sinks. The scale is set so that an ordinary team, beating and losing to a mix of opponents about equally, would sit near 100.
Who you play matters. Points depend on the two sides' ratings just before the game, so beating a strong opponent pays better than beating a weak one, and a draw between unequal teams quietly helps the underdog at the favourite's expense. Only the last three to four years count, with the older half of that window weighted at 50 per cent, which is what produces the silent annual shuffle.
For years the leader at the 1 April cut-off also collected prize money and a shield. Its design borrows from the two euro coin, a gold-coloured centre inside a silver-coloured ring. Ricky Ponting of Australia received the first in December 2002, and MS Dhoni of India accepted the last in July 2013, after which the award was dropped. The table has also been used to grant direct places at World Cups.
Monthly ratings officially reach back to October 2002, but in 2011 the council's statistician, David Kendix, ran the same formula over every result since 1981. That reconstruction confirmed how thoroughly Australia had ruled the format: 200 months at the top, far more than anyone else. Earlier decades were left out because matches were too sparse and too few nations played. Smaller nations joined gradually; Ireland earned a spot through two wins at the 2007 World Cup, and the Netherlands followed after beating Bangladesh in 2010.
