After scoring a century in his debut, he failed to come up with a century innings in the next four matches but came back with two back to back centuries against Pakistan reflecting that he has come back to form for those doubters of world cricket. With the same kind of a trend, he went without a century for the next four matches and came back with a bang against the Aussies scoring a beautiful hundred at Perth in 2006.
In the year 2007, there was a continuous patch of three Test matches, where he failed to score a century and showed his class against the Indians by scoring 104 runs at Oval, after which he scored another century during the year end -on December 2007 against Sri Lanka, as per data available on espncricinfo.
The year, 2008 can be described as his worst as far as his century scoring consistency goes, as he failed to score any century in that particular year with the highest score reading 76 against South Africa in Birmingham. It was one of his worst runs with 12 matches on a trot without a Test century, though there were a few half centuries for the Englishman. If one may add, there was another lean patch for Cook, when they played the Aussies at home during 2009, where he failed to score in that series against Australia for two months, July and August. But, he scored 3 centuries in 2009.
In 2010, he enjoyed a good year with the bat scoring four centuries, where he went without a century for four matches in a row. He played only 8 Test matches in 2011 scoring four centuries and in the process also registering his highest score of 294 runs against the Indians at Birmingham. From January 2012 – June 2012, he was only coming close to centuries but failing in the final lap (nervous nineties). He had a lean patch as per his standards - without a century for 8 Test matches. But from July onwards, he has been in prime form with four centuries in six Test matches, which includes the ongoing India-England series as well.
Cook's career stats reveal that the player has been one of the best batsmen for England since 2006 against all opponents and in all conditions. Be it - the slow and low sub continental conditions or the bouncy pitches of South Africa and Australia, or the seaming conditions of New Zealand, he has thrived magnificently.
