They used rate of fatal accidents instead of VFR into IMC. Restricting it to VFR into IMC would include all Angel Flight but not all private accidents, so would look even worse for Angel Flight. I'm sure someone can do that statistic if you want it.
The statistic DID show angel flight was more dangerous than normal private flights. From the report, the probability that passenger carrying Angel Flight fatal accident rate is greater than other private flights: 96.8%.
And for Angel flight, who are claiming that non-passenger flight were excluded, that number is there too: the probability that the combined flights Angel Flight fatal accident rate is greater than other private flights: 82%
ATSB produced the statistics. The numbers and methodologies are documented. If you want to dispute the methodologies and produce your own numbers feel free - that is why it is important that the information is published. But you can't claim that ATSB didn't produce the numbers. If you do your own calculations, you should publish the workings as well so that people can see how you came to a conclusion.
