It has taken until the final Test of the series, but finally England have their batting order correct.
They may still have been staring down the barrel of a rare Ashes whitewash had it been this way from Brisbane, but for the longer term Kevin Pietersen is the right man to bat at number four.
True, Paul Collingwood struck a double century in Adelaide at four, but other than that is has been slim pickings and England's go-slow tactics there, where Collingwood was a culprit, ultimately brought them undone.
Whatever the uncomfortable truth might have been behind Pietersen's mid-match elevation in Melbourne, it should now be forgotten.
At the MCG, it reeked of desperation and duly crashed, but the 108-run stand for the third wicket in Sydney pointed to a brighter future for England's middle-order.
By force of personality, or by dint of his unusual ability, Pietersen has the rare ability to influence his team-mates.
Number three Ian Bell is not naturally an enforcer, but he certainly has some strong shots at his disposal. He appears happier at the crease when Pietersen is there, freer to take a more organic approach to his strokeplay knowing that runs are coming from the other end also.
Batting with Collingwood, Bell can seem ill-at-ease and contrived trying to force the issue when the scoring rate drops. He is a better technician, with a wider repertoire, than Collingwood, and the onus usually falls on him.
OK, it didn't work completely on day one in Sydney, but the formation needs time to bed in and it was still England's second-highest third-wicket stand of the series, behind the 113-run effort in Adelaide.
What is more, Pietersen may be less prone to the brain explosion which brought his demise with the added responsibility that batting at four brings. There is only one way to find out, and England are on that road of discovery.
The knock-on effect can also be felt further down the order. Pietersen and Andrew Flintoff, two similar batsmen, rarely bat well together, but are often required to at five and six.
But, with Collingwood at five, the balance that was evident during England's third-wicket stand can be replicated when the likes of Flintoff and Collingwood, or Flintoff and Bell, come together. At times during the first evening at the SCG, Freddie and Colly were great together.
Of course, different men will fall at different times, thus altering the make-up of each partnership Test by Test. But with more grunt higher in the middle-order, and the greater balance it brings, the plan should succeed more than it fails.
