===Fourth round of testing===
On 2 February 2006, Muralitharan underwent a fourth round of biomechanical testing at the University of Western Australia. There had been criticism that the previous round of tests in July 2004 did not replicate match conditions due to a slower bowling speed in the laboratory tests. The results showed that the average elbow extension while bowling the 'doosra' delivery was 12.2 degrees, at an average of {{convert|53.75|mph|km/h|abbr=on}}. The average for his off-break was 12.9 degrees at {{convert|59.03|mph|km/h|abbr=on}}.<ref name="Murali cleared by yet more tests">{{Cite news |date=4 February 2006 |title=Murali cleared by yet more tests |url=http://news.bbc.co.uk/sport2/hi/cricket/4680246.stm |work=BBC Sport Cricket |location=London |access-date=30 March 2008 |archive-date=7 December 2007 |archive-url=https://web.archive.org/web/20071207010208/http://news.bbc.co.uk/sport2/hi/cricket/4680246.stm |url-status=live }}</ref>
