I've now ploughed my way through a few recent ATSB reports and you can, I believe, with practice, identify precisely where the CASA copy and paste appears to have been slid into the report.
I absolutely agree that you don't actually get the picture of the ATSB pattern until you have been through a number of reports. Then you start to see a range of tricks. The ting is that its time consuming ad few people will do it, so the ATSB gets away with it.
I'm also deeply suspicious that the delay in publishing the reports is intentional to make it harder to cross check anything.
